If f(x)= x2 + 1 and g(x) = 3x + 1, find 2f(1) + 3g(4)<br><br> •45<br> •43<br> •42
Alex73 [517]

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}
