Answer:
If there are more than one thing on the x. Let me just show you because I can't really explain it very well, so I'm sorry.
Step-by-step explanation:
5x+23=10
23(x^2)+5=27
There is more than one thing acting on the x to get it into a number.
(f+g)(x)=f(x)+g(x) = x³-x +x³ +2x²-10=2x³ + 2x²-x-10
(f+g)(x)=2x³ + 2x²-x-10
Answer: 10
Step-by-step explanation:
f(x)= 3 (2) - x + 6
f(x)= 6 - 2 + 6
f(x)= 4 + 6
f(x) = 10
For this case we have the following functions:

By definition of composition of functions we have:

Then substituting:

So:
