The equation given is the equation for a parabola.
It is a function of x, which means that a value for y can be determined for any chosen value of x.
However, as it is written, it cannot be solved.
If a particular value of "y" is given, then the graph can be used to solve the equation.
For example. Use a graph to solve:
