<p>So I take an AP Calculus course and my teacher gives us these problems…usually she’s around to help us out, but we had a double snow day on the days I’m permitted to stay after school and she is not answering her e-mail soo here’s the problem.</p>
<p>Given the function f defined by f(x)=x^3-x^2-4x+4
a. find the zeros of f
b. Write an equation of the line tangent to the graph of f at x=-1
c. The point (a,b) is on the graph of f and the tangent to the graph at (a,b) passes through the point (0,-8) which is not on the graph of f. Find the values of a and b.</p>
<p>For a I got 1, 2, and -2 and for b and c I have no idea…can anyone help me out</p>
