Which values of x do we choose? Radicals
For the following functions, think about "How to graph like a math teacher." Math teachers want to sketch graphs quickly and efficiently and choose values of x that work "nicely" in the equation and generate integer values of y, thus making it easier to graph.
Which points in the graph
- are best found by inspection?
- are best found by substitution?
- are best found by symmetry?
