Howdy, Missy. First off, what does (fxg)(x) mean to you? or (f*g)(x)?
OpenStudy (anonymous):
multiply
OpenStudy (mathmale):
That's right, Missy! So, would you go ahead and multiply the two functions together? In other words, multiply: (3x-7)(-2x+6)
OpenStudy (anonymous):
ok thanks
OpenStudy (mathmale):
And then, Missy, substitute the x-value 4, and then you will have completed the problem solution.
