**NOTE** -

#### Explanation:

The given function

The graph of this function is given below :-

graph{3sin(2x)+5 [-25.66, 25.67, -12.83, 12.83]}

**OR**

You can use another test to check if it is not one-one function :-

Draw a horizontal line parallel to X-axis which goes through the graph ;

if it cuts the graph at more than one point then it is not one-one function.

**This is not an Invertible function since it is NOT one-one function.**
