# How do you find the x and y intercepts for #f(x) = x^3 - 2.91x^2 - 7.668x - 3.8151#?

##### 1 Answer

#### Answer:

Scale the polynomial to make one with integer coefficients then use the rational root theorem to help find the zeros.

Intercepts are

#### Explanation:

The intercept with the

Let

Let

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
