Q:
# Please help. I don't understand where to start with this one. If the slope of a strictly decreasing function at the point (a, b) is –4, what is the slope of the inverse of the function at the point (b, a)? a. -1/4 b. –4 c. –1 d. The slope cannot be determined without knowing the equation of the function.

Accepted Solution

A:

just assume the equation is y=-4x

to find the inverse you switch x and y so your equation becomes x=-4y, and then solve for y and you get, y=(-1/4)x so the slope is A)-1/4
