Question 56179
The reason that we can't answer your question is because we can't see your graph:
This is an exponential graph, it's domain is all real numbers and its range is y>0:
{{{graph(300,200,-10,10,-10,10,2^x)}}}
This is a parabola, it's domain is all real numbers and its range is {{{y>=0}}}:
{{{graph(300,200,-10,10,-10,10,x^2)}}}
This is a hyperbolic graph, its domain is all real numbers except x=0, and its range is all real numbers excepy y=0:
{{{graph(300,200,-10,10,-10,10,1/x)}}}
All these graphs have the same basic shape but can be rotated and reflected, translated and stretched.
I hope that helps you figure out whatever it is you're trying to figure out.
Happy Calculating!!!
