Answer:
-----> Graph C
-----> Graph A
-----> Graph B
-----> Graph D
-----> Graph E
Step-by-step explanation:
we have
case a)
Find the domain
we know that
The radicand must be greater than or equal to zero
so
The domain is the interval -----> [1,∞)
All real numbers greater than or equal to 1
The range is the interval -----> [0,∞)
All real numbers greater than or equal to 0
case b)
Find the domain
we know that
The radicand must be greater than or equal to zero
so
The domain is the interval -----> [0,∞)
All real numbers greater than or equal to 0
The range is the interval -----> [0,∞)
All real numbers greater than or equal to 0
case c)
Find the domain
we know that
The radicand must be greater than or equal to zero
so
The domain is the interval -----> [0,∞)
All real numbers greater than or equal to 0
The range is the interval -----> [-1,∞)
All real numbers greater than or equal to -1
case d)
Find the domain
we know that
The radicand must be greater than or equal to zero
so
The domain is the interval -----> [0,∞)
All real numbers greater than or equal to 0
The range is the interval -----> (-∞,0]
All real numbers less than or equal to 0
case e)
Find the domain
we know that
The radicand must be greater than or equal to zero
so
The domain is the interval -----> [1,∞)
All real numbers greater than or equal to 1
The range is the interval -----> (-∞,0]
All real numbers less than or equal to 0
