Calc AB

Suppose that f(x) is an invertible function (that is, has an inverse function), and that the slope of the tangent line to the curve y = f(x) at the point (2, –4) is –0.2. Then:
(Points : 1)

A) The slope of the tangent line to the curve y = f –1(x) at the point (–4, 2) is –0.2.

B) The slope of the tangent line to the curve y = f –1(x) at the point (2, –4) is –5.

C) The slope of the tangent line to the curve y = f –1(x) at the point (2, –4) is 5.

D) The slope of the tangent line to the curve y = f –1(x) at the point (–4, 2) is –5.

E) The slope of the tangent line to the curve y = f –1(x) at the point (–4, 2) is 5.
