If you are looking at a graph of a quadratic equation, how do you determine where the solutions are? I am confused on this question in my algebra. Please help if possible, thanks

Hint: When you plug a "solution" x-value into the equation, what do you get for y? Where do you put "solution" points on your graph? How are "roots", "zeroes", and "solutions" related?
