Answer 1

The range is the y-values of the points. What are the y-coordinates of these points?

Answer 2

would it be {-2, 1}

Answer 3

hint:
we have this:
\[\Large f\left( 2 \right) = 1,\quad f\left( 4 \right) = 1,\quad f\left( { - 4} \right) = - 2\]
now, please apply the definition of the range of a function

Answer 4

yes! correct!
