We know so we will use x=9 as the starting point. Next we need the slope of the tangent line to f(x) at x=9. So we need to find the derivative f’(9).

We know so we will use x=9 as the starting point. Next we need the slope of the tangent line to f(x) at x=9. So we need to find the derivative f’(9). We can rewrite the function as and use the shortcut rule for the derivative of a power function.
