Let f(x) be a quadratic polynomial such that f(-4) = -22, f(-1)=2, and f(2)=-1. Let g(x) = f(x)^16. Find the sum of the coefficients of the terms in g(x) with even exponents. (For example, the sum of the coefficients of the terms in -7x^3 + 4x^2 + 10x - 5 with even exponents is (4) + (-5) = -1.)

I did? Sorry! Ok, I will try to find it.....

After a lot of searching, I still can't find it! Did you see it, Melody?

I JUST FOUND IT! https://web2.0calc.com/questions/polynomial-help-please_2

(BTW, wasn't me! someone else posted it)

But... I still need help to solve it, and that link just gives an answer. Please help!

Well I asked questions on that previous post.

No one has answered them.

I will admit up front that I have not finished the question.

Finding f(x) is not super difficult but I did not finish the next step.

Maybe there is a nice short cut.

have you found f(x) yet?
