How to graph
x/x^2-1 = y from scratch?
Cause theres no turning pts. Do we just plot the pts?
i assume it's:
y is a function so,
vertical asymptotes at points where f(x) is undefined:
x
2-1=0
x=1 and x=-1
horizontal asymptotes; behaviour of y as x->+-infinity:
.'. as x-->+-infinity, f(x)-->0
when x=0, f(0)=0
also f(x) is odd
when x is +ve f(x) is +ve
when x is -ve f(x) is -ve
try graphing now by drawing in the horizontal/vertical lines (using broken lines) and then using the other information
nb: remember a function can cross its horizontal asymptotes but not its vertical asymptotes
