For the point 1)

- The domain will be: (note that this is not an interval, it is a set of two points)


\mleft\lbrace-3,2\mright\rbrace

-The range is the set R of all real numbers (since the line extends to infinite)

-The first graph is NOT a function

For the point 2)

-The domain will be the interval


(-5,5\rbrack

-The range is the interval:


\lbrack-2,2\rbrack

-The second graph is a function.
