Question

Previous tutor was disconnected. steps understood answers just needed.For each graph below state whether if it is one to- one? Thank you for your time

Answer 1

SOLUTION

The horizontal line test for one-to-one function explains that a function is one-to-one if the horizontal line cuts the function at only one point.

Hence, considering the graph naming the vertically from left to right

1. Graph 1 is one-to-one since the horizontal line cut the graph once (YES)

2. Graph 2 is one-to-one since the horizontal line cut one of the graphs at a point (YES)

3. Graph 3 is not one-to-one since the horizontal line cut the graph more than once (N0)

4. Graph 4 is not One=to=one since the Horizontal line did not cut the graph at any point (N0)

5. Graph 5 is one-to-one since the horizontal line cut one of the graphs at a point (YES)

6. Graph 6 is one-to-one since the horizontal line cut one of the graphs at a point (YES)
