Use the Power Rule to find f ′(x) for f(x) = (x + 4)(x − 3) by first expanding f(x). Then, find the equation of the line tangent to f(x) at x = 3. Homework Help ✎

In order to find the equation of the tangent line at x = 3, you will need to find a point on the line and the slope at x =3.

To find a point, evaluate f(3)=_________

To find the slope, evaluate f '(3)= ________

Put it all together in point-slope form: yy1 = m(xx1)
