Answer:

Functions - a and c
Non- function - b

Step-by-step explanation:

This is verified with a vertical line test.

If a graph of a function is intersected by a vertical line at more than one point, it is not a function. This comes from the definition of a function.

We can see that the graphs a and c pass the vertical line test but the graph b fails, since at any positive x, the vertical line has two - y coordinates per each x- coordinate.

Help pls I really need it

Answer:

Infinite number of solutions

Step-by-step explanation:

when you solve for V, you notice that the term in "v" goes away, and you end up with a true statement:

2 = 2

This is a true statement no matter what values the variable V has, so it is true for all possible (infinite) values of "v".
