Answer:
n>0, 2 solutions.
n=0, 1 solution.
n<0, No solutions.
The equation x² is a standard parabolic function. If "n" is considered the "y" value, we can simply look at the equation as:
y= x²
Now, if you know what the graph is this equation looks like, we can see that it never extends into the negative y axis. This means that there is no solution when, in this case, n<0.
The graph also has a vertex when n=0 (remember n is considered the y value), meaning that there is one solution here.
Finally, the graph has two x values for any POSITIVE y value, meaning whenever n>0, there are two solutions.
