Step-by-step explanation:
we have
we know that
The radicand must be greater than or equal to zero
so
solve for x
Adds 3 both sides
Multiply by -1 both sides
Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so
The domain of the function is the interval (-∞,-3]
For x=-3 ---> the value of y=0
The range is the interval {0,∞)
therefore
