The tangent line to the graph of $y=g(x)$ at $x=4$ has equation $y=-3x+11$. What is the equation of the tangent line to the graph of $y=g(x)^3$ at $x=4$? The answer should be in the form $\verb#y=mx+b#$.

How about the following:

You could just use g(x) = -3x+11, of course, to get the same answer!
