25 POINTS! PLEASE HELP ME!!!!!

Describe the graph of the function f(x) = 15x^3 - x^2 + 3x - 2. Include the y-intercept, x-intercepts, and the shape of the graph. Show all of your work for finding x & y-intercepts.

Answer 1

The y-intercept would be (0,-2). To find that just plug in 0 for all the x values. One of the x-intercepts would be 2/5 and the other 2 are imaginary values, meaning you would have to do synthetic division with 2/5 to find the other 2 values. The other zeros are x=
`\frac{-1+i{√(11)}}6   \frac{-1-i{√(11)}}6`
