Question

A function is shown in the table below.

x f(x)
–4 2
–1 –4
0 –2
3 16
If included in the table, which ordered pair, (-4,1) or (1,-4), would result in a relation that is
no longer a function? Explain your answer.

Answer 1

The ordered pair that would result in a relation that is no longer a function is (-4, 1) and (1, 4) because I notice that the table of the function is equal to the function y = x² + 3x - 2, making the function have the ordered pair neither have the two ordered pairs in the function.
