Question

I need help on this question f(x) worth 20 points and please explain so I can understand

Answer 1

g(3)
so we need to see which function we need to apply to it

we have the zones, x≤-2, -2<x≤0, and x>0

-3 is less than -2 so we apply the one for zone x≤-2
7-x is that one
7-(-3)=7+3=10

g(-3)=10
