Question 957633
 Use the graph of f(x) to find the solutions to the equation f(x)=0. 
What are the solutions of the equation 2x^2=8? Use a graph of a related function whose roots answer the question.
----
x^2 = 4
x^2-4 = 0
(x-2)(x+2) = 0
x = 2 or x = -2
-------
Graph y = 2x^2-8
{{{graph(400,400,-10,10,-10,10,2x^2-8)}}}
