Answer:
16
Step-by-step explanation:
To solve this, you need to evaluate the function at f(1), which just means that you have to plug in 1 for any x you see in the equation. For example, here f(1) = 2(1) + 2 which simplifies to 4. Next find f(5). By doing the same process you will find that this is 12. The problem asks for f(1) + f(5) so by putting those values in you will get 4+12=16. Hope this helps! :)
Answer:
F(x) = 2x + 2 is the equation given.
We are going to solve this one after the other i.e solving for f(1) 1st amd then f(5) and later adding the two together.
Solving for F(1)
F(x)= 2x + 2
This means that you substitute 1 for x in the equation.
F(1) = 2(1) + 2
= 2 + 2
= 4.
For F(5)
You substitute 5 for x in the same equation.
That is,
F(5) = 2(5) + 2
= 10 + 2
= 12
now F(1) + F(5)
= 4 + 12
= 16
