The homeowork problem says this, and i need help for one , how to know if its a one to one function or not
- Determine whether it is one-to-one.
To check whether the function is one to one or not.
Consider the given function.
Use the graphical interpretation to determine the one to one function.
A function is said to be one to one function if and only if the graph of the function passes through the vertical line and horizontal line test.
From the Figure 1, it is observed that the graph of the function intersect the vertical line at single point that is (1, 1.732).
Horizontal line test:
A function is said to be one to one function if and only if the horizontal line intersect the graph of the function at most one point.
Use the graph of the function and check whether the graph of the function passes through horizontal test or not.
