Answer:
Explanation:
16. f(x)=x. f(3)=3 f(0)=0. f(-2)=-2
17. f(x)=x-2
f(3)=3-2. f(0)=0-2. f(-2)=-2-2
f(3)=1. f(0)=-2. f(-2)=-4
18. g(x)=x-2
g(3)=3-2. g(0)=0-2. g(-2)=-2-2
g(3)=1. g(0)=-2. g(-2)=-4
19. g(x)=3x.
g(3)=3(3). g(0)=3(0). g(-2)=3(-2)
g(3)=9. g(0)=0. g(-2)=-6
20. h(x)=1.2x
h(3)=1.2(3). g(0)=1.2(0). g(-2)=1.2(-2)
h(3)=3.6. h(0)=0. h(-2)=-2.4
