A vertical line has all points with the same x coordinate, but infinitely many different y coordinates. It inherently fails the vertical line test because we can pass a single straight line through more than one point on the function curve.

Put another way, the input is a single value but there's infinitely many outputs. A function must have each input produce exactly one output. This is of course only when the input is in the domain.

Given that

Kali earns $ 8 per hour.

If she worked for n hours so it would be $8n

And she worked on both monday and tuesday for x hours

So, the x hour earning is $8x and for both days it would be $2 (8x)
