Which pair of functions are inverses of each other? O
A. f(x) = 7x- 2 and g(x) = *
2+2
7
B. f(x) = 6 + 6 and g(x) = 5x - 6
O c. f(x) = V# and g(x) = 6x3
O D. f(x)= - 2 and g(x) = x+2
5

A (0,0) is at the origin.
P is at (10, -5).

Let the coordinates of B be (x,y).
Because A,  B, and P are collinear and PB : AB = 2/7, therefore
x = (7/9)*10 = 7.78
y = (7/9)*(-5) = -3.89

The distance between B and the x-axis is 3.89
The distance between B and the y-axis s 7.78

The x-axis is closer to B
