Answer:

Given the functions:


f(x) = 3x^2+2


g(x) = x-8

we have to find
(f \cdot g)(2)


(f \cdot g)(2) = f(2) \cdot g(2) ....[1]

Substitute the value of x = 2 in f(x) and g(x) we have;


f(2) = 3(2)^2+2 =12+2 = 14 and


g(2) = 2-8 = -6

Substitute these in [1] we have;


(f \cdot g)(2) = 14 \cdot -6 = -84

Therefore, the value of
(f \cdot g)(2) is, -84
