Question 103413
simplify this on the website and it gave me y - (x^2 - 4)/2x^4 = 0 
I am suppose to state what the intercept is and what it is symmetric to (y-axis, x-axis and/or origin) 
-------------------------------------
y - (x^2 - 4)/2x^4 = 0 
{{{graph(400,300,-10,10,-10,10,(x^2-4)/2x^4))}}}
---------------
Intercepts: 
Since x cannot be zero, no y-intercepts.
If y=0, x=+2 or x=-2 are the x-intercepts.
-----------------------
Symmetry: 
f(x)=f(-x) so the function is even and therefore symmetric to the y-axis.
