Question

What is the range of the function y=sqrt(x+5)

Answer 1

The correct answer is B.) y > 0

Answer 2

Range of a function is defined as those values of y, for which x is Defined.

The given function is

`y=√(x+5)`

Squaring both sides

`y^2=x+5\\\\x=y^2-5`

x is defined for ,all Real values of y.

For any real y,we get defined value of x.

That is , y ∈ R

→→y∈(-∞,∞)⇒Range
