Question

What is the range of the function y = StartRoot x + 5 EndRoot?

Answer 1

Answer:

B.

Step-by-step explanation:

Answer 2

Answer:

y greater-than-or-equal-to 0

Step-by-step explanation:

we know that

The domain of a function is the set of all possible values of x

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

we have

$y=\sqrt{x+5}$

Remember that the radicand of the function must be greater than or equal to zero

so

$x+5\geq 0$

solve for x

$x\geq -5$

The domain is the interval ----> [-5,∞)

For x=-5

$y=\sqrt{-5+5}=0$

so

The range is the interval ----> [0,∞)

$y\geq 0$
