Given f(x) = 3x − 10 and g(x) = 12x + 8, solve for (f + g)(x) and select the correct answer below. (f + g)(x) = 15x − 2 (f + g)(x) = 9x − 2 (f + g)(x) = 15x + 2 (f + g)(x) = 36x2 − 120x

So you have to multiply 12x+8 and 3x-10

So it is a binomial so what is 12x times 3x?
anonymous
  • anonymous
36

yes but don't forget to combine like terms with the x. So 36x^2. Now what is 3x * 8?
anonymous
  • anonymous
its 24 and ok

Hold on I looked at it wrong

The notation, \((f + g)(x)\) is equal to \(f(x) + g(x))\).

  • anonymous
Yes @Algorithmic is right so what is 12x + 3x?
anonymous
  • anonymous
addition now? Ok 15x?
anonymous
  • anonymous
yes and what is 8-10?
anonymous
  • anonymous
-2

Good job and when you combine them it is (f + g)(x) = 15x − 2. So which answer do you think it is A, B, C, or D?
