Hey guys i need some help with this. i know u can find f(x) by typing in the x value. but is there a way of finding out the x value using the known f(x) value?

Re: Hey

If you for example want to find the x-coordinate for y=5, you can insert a function f(x)=5 and use Calc|Evaluate with Snap to set to Intersection. When you click in the graphing area, Graph will find the x-coordinate for you where the functions intersect.
