Graphing Square Root Function
A square root function will take the shape of half of a parabola that opens left or right
- the square root is an example of an "even" root function
- all "even" root functions have a domain restriction
- the domain restriction of any "even" root function occurs at the "zero" of the radicand
- all "even" root functions are defined at the domain restriction, but this x value will yield the limiting point of the "even" root function
- the "radicand" of any radical function is the number or expression that lies inside the radical
- rational coordinates on the graph of a square root function can be found by setting the expression in the radicand equal to perfect squares and solving for the variable.
- an "even" root function may or may not have an x or y intercept, this depends on the "transformations" to the "even" root function
