Given the function defined as f(x)=x^3-(3/2)x^2-6x+10
a) Explain why f(x) must have a root between x=-3 and x=-2
b) Write an equation of the line perpendicular to the graph of f at x=0
c) Find the x and y coordinates of the point on the graph of f where the line tangent to the graph is parallel to the x-axis
Help would be GREATLY appreciated !
