Question

Which expression represents h(x)?

Answer 1

ANSWER

(f.g)(x)

EXPLANATION

From the table we can observe the following patterns:

f(-6)=12

g(-6)=-6

h(-6)=-72=12×-6

f(0)=3

g(0)=0

h(0)=0=3×0

f(6)=-6

g(6)=6

h(6)=-36=-6×6

Hence the h(x) is obtained by multiplying f(x) by g(x).

h(x)=(f.g)(x)
