How do i show the mod.

i mean i want to write a function that that gives the positive of the given y value
f(x)=|X| in the graph software

Also how do i find the derivative at a point in the software

THanks

Re: How to: Mods and Derivatives

Use f(x)=abs(x) to plot the absolute value.
Use Calc|Evaluate to evaluate the function at a given point.
