F(x) = x(x - 1) g(x) = 3x find (f*g)(6)

svetlana [45]

Step-by-step explanation:

Given functions:

f(x) = x(x - 1)
g(x) = 3x

Find (f*g)(6):

(f*g)(6) = f(6)*g(6) = 6(6 - 1)*3(6) = 30*18 = 540

In case it is a composite function (f · g)(6) the answer is different:

(f · g)(6) = f(g(6)) = f(3*6) = f(18) = 18*(18 - 1) = 306
