Question

Given that F(x) = x 2 + 2, evaluate F(1) + F(5). 38 30 15

Answer 1

F(1)=1+2=3
F(5)=25+2=27
F(1)+f(5)=3+27=30

Answer 2

B.
`F(1)+F(5)=30`

Explanation:

We have been given that
`F(x)=x^2+2`. We are asked to evaluate
`F(1)+F(5)`.

First of all, we will find F(1) by substituting
`x=1` in our given function.

`F(1)=1^2+2`

`F(1)=1+2`

`F(1)=3`

Now, we will find F(5) by substituting
`x=5` in our given function.

`F(5)=5^2+2`

`F(5)=25+2`

`F(5)=27`

`F(1)+F(5)=3+27`

`F(1)+F(5)=30`

Therefore, option B is the correct choice.
