Question

the inverse of a function a function
1. alaways
2. sometimes
3.never

Answer 1

If reflected over the identity line, y = x, the original function becomes the red dotted graph. The new red graph is also a straight line and passes the vertical line test for functions. The inverse relation of y = 2x + 3 is also a function. Not all graphs produce an inverse relation which is also a function.

Answer 2

A function and its inverse function can be described as the "DO" and the "UNDO" functions. A function takes a starting value, performs some operation on this value, and creates an output answer. The inverse function takes the output answer, performs some operation on it, and arrives back at the original function's starting value.

Answer 3

so it would be always?
