Question Analysis
This question tests the student's ability to solve a quadratic polynomial equation by graphing. The student needs to identify the x-intercept of the graph of the function .

Key Concept Explanation
The solutions to a polynomial equation are the x-intercepts of the corresponding polynomial function. For a quadratic equation with a perfect square, the x-intercept will have even multiplicity, meaning the graph touches but does not cross the x-axis.

Step-by-step Solution
1. Graph the function
