If a function is one-to-one, then its inverse is a function. true or false?

Yes, the inverse would be a function. Allow me to explain.

A function has an input x and an output y. An inverse function simply reverses the function. So for a 1:1 function, for every time x goes up by one, y also goes up one. So for the inverse of the function, it is the opposite. If I am not mistaken, every time y would go up one, x would go down one, and vice versa. That is the only part I am not 100% sure on, so I'd stick with the answer shown below.

Yes, the inverse of a 1:1 function would also be a function.

5x+10 is the correct one

hope this

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
