Question

which of the following is a one-to one function picture will be included

Answer 1

sorry if it is upside downkit might not be so hold up please

Answer 2

i know it means that the x value is connected to one y value buut idk how to figure it out here

Answer 3

Well you know right off that y = x^2 is not one-to-one, because there are two identical y values for say x = 1 and - 1. And x = 2 and -2. The y values are the same for those different x values. So although it may pass the vertical line test as a function, it is not a one-to-one function.

Answer 4

i think it should be always crescent, and continuos

Answer 5

A one-to-one function basically means that the the function itself and the inverse of the same function pass the vertical line test.

Answer 6

If it is to be one-to-one, it will have to be linear. Or at least a linear piecewise, like the first choice. That one looks like this when you graph it:

Answer 7

So if you have a graph of a function, see if passes the vertical line test. Then, if it passes, see if passes the "horizontal line test." The HLT is the same concept as the VLT.

Answer 8

@Nairz this is equal to be crescent
