Question 116693
Graph this rational function finding the asymptotes,zeros,y-intercept, and other points as needed. 
f(x)= 2x^2-8/x^2-25
-----------------------
vertical asymptote: 
x^2-25 = 0
x = 5 and x = -5
-------------------------
Horizontal asymptote: y = 2x^2/x^2 = 2
-----------------------
Zeros:
2x^2-8 = 0
x^2 = 4
x = 2 and x = -2
----------------------
y-intercept:
Let x = 0; y = 8/25
-------------------------
Graph:
{{{graph(400,300,-10,10,-10,10,(2x^2-8)/(x^2-25))}}}
