plz can any1 graph dis equation ? I really need it !!
$\displaystyle f(x)=81-x^2$
plllllllllz ! Thanks so much !
it is an inverted parabola. do you know what $\displaystyle -x^2$ looks like? it is a simple transformation. just shift the graph up 81 units and you get $\displaystyle 81 - x^2$
then you can find the intercepts if you want. do you know how to do that?
