Answer:
47
Step-by-step explanation:
So we have the two functions:
[tex]f(x)=5x^2 \text{ and } g(x)=3x-4[/tex]
And we want to find f(-3) + g(2).
So first, let's figure out their respective values:
f(-3):
[tex]f(-3)=5(-3)^2[/tex]
Square:
[tex]f(-3)=5(9)[/tex]
Multiply:
[tex]f(-3)=45[/tex]
g(2):
[tex]g(2)=3(2)-4[/tex]
Multiply:
[tex]g(2)=6-4[/tex]
Subtract:
[tex]g(2)=2[/tex]
So:
[tex]f(-3)+g(2)\\=(45)+(2)[/tex]
Add:
[tex]=47[/tex]
So, our answer is 47.
And we're done!
