GRAPH the equation, then use MENU, TRACE, GRAPH TRACE to find the RANGE (y-values) of the graph. It's easier to to find the minimum or maximum value and check which answer choice is true.

• D

Remember in order to check if a graph is a FUNCTION, it needs to pass the VERTICAL LINE TEST. The VERTICAL LINE TEST should pass through a graph ONLY ONCE for it TO BE A FUNCTION. If it crosses more than once it is not a function.

You can use the DEFINE feature because it says the word EQUIVALENT.

x:=2

y:=3

Then type the original problem and type each answer choice and check which ones are equivalent.
