Which of the following functions is graphed below

Remark

A function is defined as 1 y value per x value. The y values can be the same for 2 x values, but the x values must have just 1 value associated with it. I am describing a vertical line test for a function. This is a function.

A 1 to 1 function means that the function obeys the horizontal line test. That means that for every x there is only 1 y value.

A

This graph is both a function and a 1 to 1 function. So the answer is A.

None of the other answers are this complete and one of them is wrong.

B

B is wrong. It is a 1 to 1 function.

C

C is wrong. The graph is a function.

D

D is wrong. No y values are duplicated.

black lol

step-by-step explanation:

h

i can tell you jamal now has 3 cookies xd

tommy has 2.

this made me lol.

both equations and proportions are better.
