How do you use the horizontal line test to determine whether the function #f(x)=1/8(x+2)^2-1# is one to one?

The horizontal line test is to drawing several horizontal lines,
A one-to-one function is a function where each
If a horizontal line crosses the function more than once, then it means that the function has more than one
In this case, doing so will give two intersections for
Example:
graph{(y-(x+2)^2/8+1)(y-1)=0 [-10, 10, -5, 5]}
The line
