Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Solving for Roots
Finding values of x such that y = 0 involves solving the equation for its roots. This means determining the x-values where the function intersects the x-axis. In algebra, this often requires setting the equation equal to zero and manipulating it to isolate x.
