Consider two linear function: f(x) and f -1(x), their lines intersect at a point with a x-coordinate of 10 and the slope of f(x) is 1/2

*Find the SI equation

*Find x= f -1 (y) then express the inverse function in terms of x: y = f-1(x)

*graph the two lines on the same set of axes, clearly showing all four x and y intercepts as well as the intersection point.
