so D
MeowLover17
  • MeowLover17
So i multiply (2x-1)(2x-1) = 4x^2-4x+1?

  • MeowLover17
Thanks can you help me on 2 others?

Consider the functions f(x) = 2x + 1 and g(x) = x2 − 10. What is the value of f[g(3)]?
MeowLover17
  • MeowLover17
A)39 B) -3 C) -7 D)-1
snivvles.com
  • snivvles.com
so x=3
MeowLover17
  • MeowLover17
I dont understand
MeowLover17
  • MeowLover17
Okay
snivvles.com
  • snivvles.com
g(x)=3^2-10
snivvles.com
  • snivvles.com
g(x)=9-10
welshfella
  • welshfella
g(x) = x^2 - 10 g(3) = 3^2 -10 = ?
snivvles.com
  • snivvles.com
g(x)=-1
MeowLover17
  • MeowLover17
yea g(x)=-1
snivvles.com
  • snivvles.com
substitute that for the x's in f(x)
welshfella
  • welshfella
right now plug in x = -1 into f(x)
MeowLover17
  • MeowLover17
-2+1 = -1
snivvles.com
  • snivvles.com
Yep!
welshfella
  • welshfella
right d
MeowLover17
  • MeowLover17
So is the answer -1?
snivvles.com
  • snivvles.com
yeah

Thanks guys :D

Given f(x) = 3x − 10 and g(x) = 12x + 8, solve for (f + g)(x) and select the correct answer below.
MeowLover17
  • MeowLover17
(f + g)(x) = 15x − 2 (f + g)(x) = 9x − 2 (f + g)(x) = 15x + 2 (f + g)(x) = 36x2 − 120x
snivvles.com
  • snivvles.com
k hang on
welshfella
  • welshfella
3x -10 + 12x = 8
welshfella
  • welshfella
now simplify
snivvles.com
  • snivvles.com
ok so its pretty much f(x)+g(x)
welshfella
  • welshfella
* thats + 8 not = 8
MeowLover17
  • MeowLover17
okay so i get 15x-10=8
MeowLover17
  • MeowLover17
15x=-2
snivvles.com
  • snivvles.com
so (f+g)(x)=15x-2
MeowLover17
  • MeowLover17
x=-7.5?
snivvles.com
  • snivvles.com
no the answer is (f+g)(x)=15x-2
MeowLover17
  • MeowLover17
Oh okay thank you, how did you get to that?
snivvles.com
  • snivvles.com
I added f(x)+g(x)
MeowLover17
  • MeowLover17
I see
welshfella
  • welshfella
3x -10 + 12x + 8 = 15x - 2
snivvles.com
  • snivvles.com
so 3x-10+12x+8
snivvles.com
  • snivvles.com
that equals 15x-2
MeowLover17
  • MeowLover17
ohhhhhh okay thanks guys <3
snivvles.com
  • snivvles.com
no problem.
