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

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
