Question

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

y greater-than-or-equal-to negative 5

y greater-than-or-equal-to 0

y greater-than-or-equal-to StartRoot 5 EndRoot

y greater-than-or-equal-to 5

Answer 1

B.

Explanation:

Answer 2

y greater-than-or-equal-to 0

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=√(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=√(-5+5)=0`

so

The range is the interval ----> [0,∞)

`y\geq 0`
