You can put this solution on YOUR website! Same problem, different numbers.
-------------------------------------------------------------
If f(x) = x 2 + 1 and g(x) = 3x + 1, find f(-1) + 5g(-3).
Do you mean f(x) = x^2 + 1 ?
Use ^(Shift 6) for exponents.
-----
f(x) = x^2 + 1
Wherever you see x, sub -1
f(-1) = (-1)^2 + 1 = 2
---
g(x) = 3x + 1
Sub -3
Multiply by 5
Add f(-1)
