how many points need to be removed from this graph so that it will be a function? 1 point 2 points 3 points 0 points
Answer
Answer:
1 point
Explanation:
Step1: Recall function definition
A function has one - output for each input.
Step2: Check vertical line test
In the graph, there are points with the same x - value. For example, at (x = 1), there are multiple y - values.
Step3: Determine points to remove
Removing 1 of the points with the same x - value (e.g., one of the points at (x = 1)) will make the graph pass the vertical line test and be a function.
