Answer:
540
Step-by-step explanation:
f(x) = x(x - 1)
g(x) = 3x
(f* g)(x) = x(x - 1) 3x
= (x^2 -x) * 3x
= 3x^3 -3x^2
=3x^2(x-1)
Let x = 6
(f* g)(6) = 3*6^2( 6-1)
= 3*36 *5
540
Answer:
540
Step-by-step explanation:
(f*g)(6)=f(6)*g(6).
Now we need to find f(6) and g(6). Once we find their values we multiply them.
f(6) means to replace x in x(x-1) with 6:
6(6-1)
6(5)
30
So f(6)=30.
g(6) means to replace x in 3x with 6:
3(6)
18
So g(6)=18.
(f*g)(6)=f(6)*g(6)=30*18=540.
