The graph is attached.
Explanation:
You have the following function:
By definition, the input in the independent value and the output is the dependent value.
Therefore, you must give values to x (input values) and substitute them into the function to obtain y for each value (output values).
Then:
x=-1

x=-0.5

x=0

x=0.5

x=1

Table:
x | y
-1 | 2
-0.5 | -0.25
0 | -1
0.5 | -0.25
1 | 2
