What ones are functions and which are not pls help

Functions: the chart with number values, the dot graph, and the middle graph on the right

Not functions: the top graph on the left with the vertical line, the graph with the circle, and the bottom right graph

Any graph that doesn’t pass the vertical line test is not a function. You can do this by starting at the top of the graph and drawing a line straight down through what you are testing. If you pass through the line or circle more than once it is not a function.
If you look at the number values if the x value repeats more than once it is not a function.

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer

For being nice i appreciate it but abc
