What characteristic is true for all relations that are functions

First option, the graph of the relation passes the vertical line test.

Step-by-step explanation:

A function is a relation that maps elements from a set (the domain, the x-values) into elements from another set (the range, the y-values)

Where the only condition we have is that each element from the domain can be mapped into only one element from the range.

So if we draw a vertical line at any point of the graph, it can intersect the graph of the function a maximum of one time. (this is known as the vertical line test)

Then the correct option is that the graph of the relation passes the vertical line test.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

the answer is c just got it on ed
