Question

Which ordered pair can be removed so that the resultinggraph represents a function?Гу543+.2+O (-2,2)O (1,3)O (5, 4)O (-4,-4)1 +.-5 4 3 -2 -111 2 3 4 5 x.-27-37-4+-5

Answer 1

After observing the ordered pairs given, the answer is

B. (1, 3)

Reason:

It is not possible to draw a function with two identical values of x.

As you can see, Grace, we already have the ordered pair (1, -2), therefore a second value of x, using the same value (1) is not possible within the same function.

Removing this point, all values of x will have just one possible y
