Give the slope of the tangent line at P and computethe equation of this tangent line.Note: You may want to recall that, in general, the slope of the tangent line at x = a isin fact given by the derivative of f at x = a or the instantaneous rate of change of f atx = a. As discussed in class, the instantaneous rate of change is viewed as the limit asI + a of rates of change Le-1@ Put differently, given the curve y = f(x), the slopeof the tangent line at P(a, f(a) can be interpreted as a limit of slopes of secant linesPQ as Q comes closer and closer to P along the curve, i.e.f(x) – f(a)limI- aThis limit can also be written as the limit of a difference quotient asf(a+h) – f(a).limhAs such, in our case, since a=1, we deduce that f'(1), which comes fromf'(1) = limf(x) – f(1)= limf(1+h) – f(1)I - 1hgives us nothing but the slope of the tangent line at P(1, –1). You may want to note thatwe have already computed these things in part a), and that you may just use the answer off'(1) to give the slope of the tangent line at P(1, –1).
