How do you find the x and y intercepts for #f(x) = x^3 - 2.91x^2 - 7.668x - 3.8151#?
Scale the polynomial to make one with integer coefficients then use the rational root theorem to help find the zeros.
The intercept with the
By the rational root theorem, any rational zeros of this polynomial are factors of
So the zeros of
The corresponding values of
So the intercepts with the
