Let f(x) = x + 9 and g(x) = x – 3. What is f(x) • g(x)? Is this the answer? x^2 + 6x – 27

OpenStudy (anonymous):

f(x) g(x) = (x+9)(x-3)

OpenStudy (anonymous):

yea that looks about right

OpenStudy (anonymous):

multiply them with each other : (x+9)(x-3) x^2+6x-27 You are right :)

okay thank you. I wasn't really sure. :)
