Question

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

•45
•43
•42

Answer 1

Answer:

the answer is 43.

Step-by-step 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

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