If a(x) = 2x - 4 and b(x) = x + 2, which of the following expressions produces a quadratic function?
(ab)(x)
(a-b)(x)
(a + b)(x)

a(x) * b(x)  will give a quadratic function

Step-by-step explanation:

A quadratic function is one with an x^2 term

a(x) = 2x - 4 and b(x) = x + 2

a(x) + b(x) will only have an term with the highest power of x

a(x) - b(x) will only have an term with the highest power of x

a(x) * b(x) will only have an term with the highest power of x^2

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
