Question

If f(x)= x2 + 1 and g(x) = 3x + 1, find 2f(1) + 3g(4)

•45
•43
•42

Answer 1

the answer is 43.

Explanation:

We have functions

`f(x) = x^2+1`

`g(x)=3x+1,`

and we want to evaluate

`2f(1) + 3g(4)`

For this we first evaluate
`f(1)` and
`g(4)` separately:

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

`g(4)=3(4)+1=13`

Therefore

`2f(1) + 3g(4)= 2(2)+3(13)=43`

So we have

`\boxed{2f(1) + 3g(4)=43}`
