Functions I need help with 14-17

14) No. 15) No. 16) Yes. 17) Yes.

Explanation:

When something is not a function, you can either use the vertical line test which involves drawing a line going up and down to see if the graph hits the line more than once. If this is the case, it is not a function. Or the input or x value of a function cannot have more than one

output or y value.

The line x = |y| on the graph of #14 is not a function because there is more than one y value for a single x value. This also hits a vertical line more than once.

The table on #15 is not a function because their is more than one y value per x value. It also hits a vertical line more than once.

The equation y = 1/4x is a function because there is only one output for each input. This also does not hit a vertical line more than once

The equation x = y - 1 is a function because it is simply a rearanged version of y = x + 1 which has only one output for each input. It also does not hit a vertical line more than once.
