What is the range?
A. All real numbers
B.
C.
D.

The range of a function is the set of all possible output values (y-values) that the function can produce. Knowing how to determine the range is crucial, especially in understanding the behavior of different mathematical functions, like polynomials, trig functions, and rationals. Picking a range could change the way you perceive the function entirely!

If you want to delve deeper into this topic, exploring function graphs and analyzing their behavior at extremes can be beneficial. Look into resources that break down the concept of domain and range with visuals, as seeing the actual graphs makes comprehending ranges a whole lot easier!
