Answer:
1. 15
2. 3
Step-by-step explanation:
These are functions of functions. You always solve the inner function first.
For number 1, the inner function is g(1) so you plug in 1 for the g function. g(1)=1+4 = 5
Since g(1)=5, you can replace g(1) with 5. Now you have f(5).
Plug in 5 for the function of f.
f(5)=3(5)=15.
For Number 2, it is the same steps but with different numbers and functions. h(0)=(0)²-1 = -1
g(-1)=-1+4=3
