Answer:

f(5) = 75

Step-by-step explanation:

The function is f(x) = 2x^2 + x(100 - 15x).

Evaluate this function at x = 5: replace each instance of x with 5:

f(5) = 2(5)^2 + 5(100 - 15·5)

Order of operations rules require evaluating the expression enclosed in parentheses first. We get:

f(5) = 2(5)^2 + 5(100 - 15·5)

= 50 + (100 - 75), so that:

f(5) = 50 + 25 = 75

f(5) = 75
