Answer: Choice C</h3><h3>
{ (-2,2), (0,2), (7,2), (11,2) }</h3>
Here we don't have any repeated x values.
In choice A, x = 2 repeats. In other words, x = 2 leads to multiple y outputs. So this is not a function. Choices B and D are similar stories. A function is only possible if every x leads to exactly one y value only. The graph must pass the vertical line test.
Side note: the y values can repeat, but the function won't be one-to-one.
Answer:
It is a function.
Step-by-step explanation:
This relation <u>is</u> a function because it does not repeat any x values in the set of data points.
A function is a set of points where the input values, or x values, do not repeat themselves.
Hope this helps!
