Using pythog:-
if the sum of the square of the shorter sides equal to the square of the longest one 
it means they represents a right triangle.

100 points and brainliest. What’s Deshawn’s mistake? What’s the correct answer?
Blababa [14]

a test to see if it is a function is a vertical line test, if you draw a straight line and the line intersects at 2 points, it is not a function.

in this case, (-2,-2) is an open hole, which means the value where it is placed is just around that value so not exact.

the vertical line test would work if it was a closed hole, and one or both points (-2,3) and (-2,-2) would have to be removed.

the mistake that deshawn made was that he mixed up the vertical line test with horizontal instead and has deduced that since a horizontal line has intercepted both points, they must be removed.

this graph is, in fact, a function since the open hole is not exactly under (-2,3)
