Which of the following strategies can be used to find the x-intercepts/solutions of a quadratic function?

• On a multiview calculator: press "table" and type in the equation , press "enter" 5 times, and scroll up or down the table to find the value(s) where y = 0

• By hand: set the quadratic equation equal to zero and solve using 1 of the methods we have learned in class (the Square Root Method, Factoring, or the Quadratic Formula)

• Visually: find the point(s) where the graph touches or crosses the x-axis.

• All of these strategies are valid.
