Which function has an inverse that is a function ?

C

Step-by-step explanation:

Step-by-step explanation:

A fuction has an inverse if it passes vertical line test.

is a horizontal U shaped graph . when we draw a vertical line then it crosses the inverse graph at two points. So it is not a function.

Inverse graph is a vertical line that does not pass vertical line test. so it is not a function.

Inverse graph is a graph of a line (linear function). Linear function always passes vertical line test. Inverse is a function

Inverse of absolute funciton does not pass vertical line test, so it is not a function.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
