Let f(x) be the polynomial \(f(x)=x^7-3x^3+2.\)
If g(x) = f(x+1), what is the sum of the coefficients of g(x)?
incorrect answer deleted. See answer #4
it was marked as wrong when i entered two...
huh... turns out the answer is 106
I'll have to look at this one.
getting old or something, see answer #4
g(1) is f(2), and the sum of the coeffcients is g(1), so the answer is 128 - 24 + 2 = 106. :)
