You can put this solution on YOUR website!
y=x^4-5x^2+4
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+x%5E4+-5x%5E2+%2B4%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10,
x^4 -5x^2 +4).
X INTERCEPTS=-2,-1,1,2
Y INTERCEPT=4
YOU GET THE INTERCEPTS BY EXAMINING THE GRAPH.
YOU KNOW THE Y INTERCEPT=4 FROM THE EQUATION.
THE X ANSWERS ARE RIGHT ON THE GRAPH X LINE.
