Final answer:
To find f(5) for the given function, substitute x with 5 and evaluate the expression which results in 22.
Explanation:
To find f(5) for the given function, f(x) = (2x + 1)(x - 3), we substitute x with 5 and evaluate the expression.
So, f(5) = (2(5) + 1)(5 - 3) = (10 + 1)(5 - 3) = 11 * 2 = 22.
