Answer:

47

Explanation:

So we have the two functions:

$f(x)=5x^2 \text{ and } g(x)=3x-4$

And we want to find f(-3) + g(2).

So first, let's figure out their respective values:

f(-3):

f(-3)=5(-3)^2

Square:

f(-3)=5(9)

Multiply:

f(-3)=45

g(2):

g(2)=3(2)-4

Multiply:

g(2)=6-4

Subtract:

g(2)=2

So:

$f(-3)+g(2)\\=(45)+(2)$

Add:

=47

So, our answer is 47.

And we're done!
