How would I graph these two functions on a calculator?

I need to find domain, range, zeros, etc., along with a sketch of graph. Or would it be easier to graph by hand? how? Thanks!

The first one can be put in as into the calculator

The second one is no good with a calculator because there are two variables. Sketch it by hand and you can find intercepts that depend on the value of a (y=0 at x=a,-a and x=0 when y=a). You can find the domain by making sure the what is under the radical is and you can find the range by solving the equation for x, and then finding the domain of that new function (you are finding the domain of the inverse function) - August 7th 2009, 12:01 PMdhiab

I'm still confused about this graph...http://www.mathhelpforum.com/math-he...60aa7cfc-1.gif

I need to find domain, range, even/odd etc. - August 9th 2009, 10:51 AMAmer
