an x value can have one y value only for it to be a function of only x
calculusxy
  • calculusxy
But how is that answering the question? @dan815
dan815
  • dan815
look at the pic you attached
calculusxy
  • calculusxy
How would I figure out the x- and y-intercepts ?
dan815
  • dan815
what is y when x=0,y-int what is x when y=0, xint
calculusxy
  • calculusxy
So for like A, would it be: y-intercept : (0,4) x-intercept: (1,0) ?
dan815
  • dan815
x-intercept: (1,0) and (-1,0)
calculusxy
  • calculusxy
Oh yeah. Thanks. Can I go over with you for the other three as well?
dan815
  • dan815
okay
calculusxy
  • calculusxy
Give me a moment please.

I am confused on B.
calculusxy
  • calculusxy
This is a function, but it doesn't look like a linear function. I wish I knew the slope, and then figure out "b."
dan815
  • dan815
you work with the data only
dan815
  • dan815
what is y when x=0,y-int what is x when y=0, xint
calculusxy
  • calculusxy
Oh. y-int : (0,-3) x-int : (19,0)
dan815
  • dan815
yes
calculusxy
  • calculusxy
C...
calculusxy
  • calculusxy
y-int : (0,10) x-int : (4.0)
calculusxy
  • calculusxy
And then D... y-int: (0,-1) x-int : (1,0) and (-1,0) ?
dan815
  • dan815
C) y-int : (0,10) x-int : (4,0) and (-2,0)
calculusxy
  • calculusxy
Sorry missed the other. But thanks.
dan815
  • dan815
D is right
calculusxy
  • calculusxy
I have another question.
dan815
  • dan815
ok
calculusxy
  • calculusxy
Find the input for the following function with the given outputs. If there is no possible input for the given output, explain why not. x = ? \[f(x) = \sqrt{2x - 6}\] \[\rightarrow f(x) = 10\]
anonymous
  • anonymous
d is correct
dan815
  • dan815
\[10=\sqrt{2x-6}\\ 10^2=2x-6\\ 10^2+6=2x\\ \frac{(10^2+6)}{2}=x\]
dan815
  • dan815
x=53
calculusxy
  • calculusxy
x = 53 ?
calculusxy
  • calculusxy
Okay. Thank you. And I just wanted to make sure my answers to two other questions.
calculusxy
  • calculusxy
So this one is the same thing as the one that we just did right now but the number is different: x = ? \[f(x)=3x - 7\] \[\rightarrow f(x) = -1\] My answer is:\[x = 2\]

This one is with the four graphs/tables that I gave at first in the attachment. Question: Which of the relationships are functions? If a relationship is not a function give a reason to support your conclusion. Answer: Relationships B, C, and D are all functions because every input has only one output. However, for A, you can see that for an input, you have several outputs.
dan815
  • dan815
C is not a function
dan815
  • dan815
of x
calculusxy
  • calculusxy
So C is not a function?
