Question

The function y =3 square root –x- 3 is graphed only over the domain of {x | –8 < x < 8}. What is the range of the graph?

Answer 1

Using a graphing tool, we can see that the whole range of the function

is  y ∈ [0,∞)

Now, in the interval
 
{x | –8 < x < 8}.

The range is y ∈ [0 ; 6.708)
