See a solution process below:

Explanation:

We can write #(f * g)(x)# as:

#(f * g)(x) = (7x - 9)x^2#

We can simplify this function by multiplying each term with in the parenthesis by the term outside the parenthesis on the right side of the function:

#(f * g)(x) = (7x - 9)color(red)(x^2)#

#(f * g)(x) = (7x xx color(red)(x^2)) - (9 xx color(red)(x^2))#

#(f * g)(x) = 7x^3 - 9x^2#
