which ordered pair can be removed so that the resulting graph represents a function? (-2,2) (1,3) (5,-4) (-4,-4)
Answer
Explanation:
Step1: Recall function definition
A function has one - to - one or many - to - one mapping, i.e., for each x - value, there is exactly one y - value.
Step2: Check x - values
We check the x - values of the given points. The x - value of 2 has two corresponding y - values (y = 3 and y=-2).
Step3: Determine point to remove
To make the graph a function, we need to remove either (2, 3) or (2,-2). But (2, 3) is one of the options.
Answer:
(1, 3)
