WebUse Descartes' Rule of Signs to find the number of real roots of:f (x) = x5 + 4x4 − 3x2 + x − 6. First, I look at the positive-root case, which is looking at f (x): f ( x) = +x5 + 4 x4 − 3 x2 + x − 6. The signs flip three times, so there are three positive roots, or one positive root. Either way, I definitely have at least one positive ... WebHow do you find the zeroes of f (x)=x^5? From the graph it seems that f (x) is equal to 0 at a lot of points. • ( 2 votes) Kim Seidel 4 years ago The graph has one zero at x=0, specifically at the point (0, 0). The other points that appear to be x=0 are actually small fractions or decimal values.
