Answer:
-10
Step-by-step explanation:
You always want to solve the inner function first.
g(-2)=(-2)³+3
=-8+3
=-5
g(-2)=-5 so you can replace g(-2) with -5
Now you just have f(-5)
Solve.
f(-5)=-5-5
f(-5)=-10
Answer:

Step-by-step explanation:
So we have the equation:

Subtract 4 from both sides:

Divide both sides by -12:

Simplify and reduce:
