$$\text{Not Invertible}$$

Work Step by Step

We use the horizontal line test to see if there is any horizontal line that can pass through the function twice. If a horizontal line does pass through twice, then the function is not invertible, but if the function passes the horizontal line test, it is invertible. Doing this, we find that the function is: $$\text{Not Invertible}$$
