Does the following set of ordered pairs represent a function? {(7,4),(5, -1),(3,-8),(1,-5),(3,6)}

not a function

Step-by-step explanation:

{(7,4),(5, -1),(3,-8),(1,-5),(3,6)}

This is not a function

The input of x=3 goes to two different outputs y=-8 and y=6

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
