Question

Is {(-7,8),(5,-5),(-7,-3)(3,-4,)} a relation a function
yes or no​

Answer 1

Explanation:

A function can only have one y value for any given x value. If there is more than one value of y for a single x value it is said to have failed the ‘vertical line test.

Since there are points (-7,8) and (-7,-3) this is NOT a function.
