Answer:

(A)C,D,A,B

Step-by-step explanation:

f(x) = x^2- 2x\\g(x) = x^3-1

a) f(-2)

f(-2) = (-2)^2- 2(-2)\\=4-(-4)\\=4+4\\=8$ (C)

b) g(-2)

g(-2) = (-2)^3-1\\\=-8-1\\=-9 $(D)

c) f(-1)+g(3)

f(-1) = (-1)^2- 2(-1)=1+2=3\\g(3) = (3)^3-1=27-1=26\\f(-1) + g(3)=3+26\\=29$ (A)

d) f(5) : g(2)

f(5) = (5)^2- 2(5)=25-10=15\\g(2) = (2)^3-1=8-1=7\\f(5) :g(2)=15/7$ (B)
