One way to graph radical functions is to create a table of
values and then plot the points. Before starting the table,
first determine the domain of the function. Remember, the
radical must be greater than or equal to zero. Once this lower
limit for input (domain) values is established, create the table
of values. When graphing radicals we plot the points in the
coordinate plane. Whenever you're asked to graph anything in
Math class, the most basic way to create a graph is using an xy
table. That's what we're going to look at today in graphing
rational functions. Excuse me radical functions, we're not doing
rationals. Radicals. It's a big difference. Okay, so first thing
you want I want to remind you guys is of domain and range. The
domain is the set of all possible input values. That's really
important when it comes to square roots because you guys know
the square root of a negative number is not a real value, is not
a real solution. So in order to find the domain, the radicand
must be greater than or equal
