How to determine if a function is one to one
Asked by admin @ in Mathematics viewed by 270 People
Determine if the function is one-to-one. (5 points)
Answered by admin @
Answer: NO
Step-by-step explanation:
In order for the function to be one-to-one, it must pass the vertical line test AND the horizontal line test.
The vertical line test is where you draw a vertical line anywhere and the line will not intersect the graph more than one time. In other words, the function cannot contain a duplicate x-value.
The horizontal line test is where you draw a horizontal line anywhere and the line will not intersect the graph more than one time. In other words, the function cannot contain a duplicate y-value.
The graph provided passes the vertical line test but fails the horizontal line test. One example is that there are two x-intercepts.
