the domain is the x values we can use
range is the y values or f(x) we get from the domain
end behavior is what happens at the ends of the graph
domain seems to be all real numbers since the arrows go infinity and there aren't any discontinuities
inequality would be -∞<x<∞
set notation would be [tex]D={x|- \infty<x< \infty}[/tex]
interval notation would be [tex](- \infty,\infty)[/tex]
the range is only from 0 and up
inequality would be f(x)≥0 since it seems to approach 0, it might be f(x)>0 tho
set notation would be [tex]R={f(x)|f(x)\geq 0}[/tex]
interval notation would be [tex](0,\infty)[/tex]
end behavior
as x approaches infinity, y approaches infinity
ax a approaches negative infinity, y approaches negative infinity
