For f(x) = x2 and g(x) = (x − 5)2, in which direction and by how many units should f(x) be shifted to obtain g(x)? Up 5 units Down 5 units Left 5 units Right 5 units SOMEONE HELP FAN AND MEDAL

okay so is that x squared
anonymous
  • anonymous
or just 2x
brodybarnes35
  • brodybarnes35
yeah squared

okay, so we have \[x ^{2}\] and \[x ^{2}-10x+25\]
brodybarnes35
  • brodybarnes35
ok so what does that mean?
anonymous
  • anonymous
from your answer choices, how are you going to get the first part to the second
brodybarnes35
  • brodybarnes35
idk, idk how to do this lol
anonymous
  • anonymous
wait, you what would be easier? lol scratch everything i said
anonymous
  • anonymous
so
brodybarnes35
  • brodybarnes35
ok :)
anonymous
  • anonymous
since both expressions are squared, we can square root both of them
xapproachesinfinity
  • xapproachesinfinity
you better live it g(x)=(x-5)^2 to see what shift needed
anonymous
  • anonymous
meaning we just have x and x-5
xapproachesinfinity
  • xapproachesinfinity
leave*
anonymous
  • anonymous
so, since you are subtracting, you are either going down or to the left
brodybarnes35
  • brodybarnes35
ok
anonymous
  • anonymous
i wouldnt leave it if i were you actually
brodybarnes35
  • brodybarnes35
ok go on please :)
xapproachesinfinity
  • xapproachesinfinity
ok let's how you gonna do it
xapproachesinfinity
  • xapproachesinfinity
see*
brodybarnes35
  • brodybarnes35
ok
anonymous
  • anonymous
well we already have x and x-5, because we square rooted, and you want him to leave it as squared, thats totally fine and you can help him
xapproachesinfinity
  • xapproachesinfinity
that's not a square root? where did you see any square root?
xapproachesinfinity
  • xapproachesinfinity
Okay lets consider a function f(x)=x^2 we call it parent function
brodybarnes35
  • brodybarnes35
ok
xapproachesinfinity
  • xapproachesinfinity
if we want to move the graph of that function f(x) to right some units away i will use b units here we just do the following \(f(x-b)=(x-b)^2\) that is b units to the right away ffrom f(x) let's give this new function a name h(x) so that \(h(x)=f(x-b)=(x-b)^2\)
xapproachesinfinity
  • xapproachesinfinity
following ?
xapproachesinfinity
  • xapproachesinfinity
now we want to move f(x) to obtain g(x) look at the g(x) and tell me what do you need to do to move f such that it becomes g
xapproachesinfinity
  • xapproachesinfinity
earth to you, hello, are you there?
brodybarnes35
  • brodybarnes35
yes im following
xapproachesinfinity
  • xapproachesinfinity
so according to what i just said what can we do to shift f to get g?
xapproachesinfinity
  • xapproachesinfinity
just compare what i did with what we have?
brodybarnes35
  • brodybarnes35
i honestly dont know im guessing 5 down or to the left
xapproachesinfinity
  • xapproachesinfinity
why down and left in my explanation i have not spelled at all any thing about down or left shifting
xapproachesinfinity
  • xapproachesinfinity
i only i explained one thing; that is shift a curve x^2 to right by a b units to get (x-b)^2
xapproachesinfinity
  • xapproachesinfinity
so basically to get from f(x)=x^2 to g(x)=(x-5)^2 we need to shift f(x) 5 units to the right
brodybarnes35
  • brodybarnes35
can you just tell me the answer and explain cause you're not helping that well :)
brodybarnes35
  • brodybarnes35
oh thanks
brodybarnes35
  • brodybarnes35
so d?
xapproachesinfinity
  • xapproachesinfinity
it is not me who is not helping it is you who don't want to be helped haha
xapproachesinfinity
  • xapproachesinfinity
i was deriving you to the answer but you seem not to pay attention
xapproachesinfinity
  • xapproachesinfinity
yes it is D
brodybarnes35
  • brodybarnes35
ok thanks can you help on like 4 more???
brodybarnes35
  • brodybarnes35
are u sure?
brodybarnes35
  • brodybarnes35
@xapproachesinfinity
xapproachesinfinity
  • xapproachesinfinity
trillion times sure! and no i can't if you don't have much interest to work the problem
brodybarnes35
  • brodybarnes35
no i will i promise @xapproachesinfinity

What is the domain of the following parabola? u-shaped graph that opens up with a vertex of 2, negative 3 All real numbers x ≥ 1 x ≤ 2 y ≥ −3
brodybarnes35
  • brodybarnes35
@xapproachesinfinity
brodybarnes35
  • brodybarnes35
help me @xapproachesinfinity
xapproachesinfinity
  • xapproachesinfinity
all sort of parabolas have the domain all real number no matter what it is
xapproachesinfinity
  • xapproachesinfinity
if we speak about co-domain (range) then the story is different
brodybarnes35
  • brodybarnes35
so its all real numbers im assuming?wait no
xapproachesinfinity
  • xapproachesinfinity
if you want the reason just think is there any number that cause a function of the sort f(x)=ax^2+bx+c does not exist i mean is there a point where that graph has discontinuity
xapproachesinfinity
  • xapproachesinfinity
the answer is no, all real numbers are acceptable in the machine of parabolas
brodybarnes35
  • brodybarnes35
so no all real numbers
xapproachesinfinity
  • xapproachesinfinity
im saying all real numbers and you are saying no all real numbers
xapproachesinfinity
  • xapproachesinfinity
pay a bit of attention dear :)
brodybarnes35
  • brodybarnes35
ohhh ok it is all real numbers i apologize
xapproachesinfinity
  • xapproachesinfinity
no problem

The quadratic functions f(x) and g(x) are described as follows: f(x) = −8x2 + 7 x g(x) 0 0 1 2 2 6 3 2 4 0 Which of the following statements best compares the maximum value of the 2 functions? It is the same for both functions. f(x) has a greater maximum value than g(x). g(x) has a greater maximum value than f(x). The maximum values cannot be determined can u help on like 3 more? plz @xapproachesinfinity
