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.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
