Question

Yes or No: the table below represents a function:                ["Yes", "No"]           Why or why notthese are the options y-values ARE repeatedX-values are NOT repeatedy-values are NOT repeatedThere is no clear patternX-values ARE repeated

Answer 1

From a tabular values of x and y, for it to be a function, every x coordinate has to have exactly one y coordinate. No repetitions.

Looking at our table:

We see that there are 6 different x values.

Are there any repetitive y values?

YES!

Both x = 5 and x = -5 gives the same y value of "18". Thus, this can't be a function.

Answer:

This table doesn't represent a function because y-values ARE repeated.
