Answer:
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
