Which system of equations can be graphed to find the solution(s) to 4 x squared is equal to x squared plus 7 ?

To find where 4x² equals x² + 7 by graphing, graph each side as a separate expression for y: y = 4x² and y = x² + 7. The x-coordinates where the graphs intersect make the two expressions equal. Choice C gives exactly these two equations.
