Domain and Range of Square Root Function

Range is:

• All x values, from left to right.

• All y values, from left to right. 

• All y values, from bottom to top.

• All x values, from bottom to top.

What type of function is shown?

• cube root

• square root

• logarithm

• exponential

What is the RANGE of this square root function?

• all real numbers

Find the domain and range of the function
Hint:  Use a scratch graph to help you visualize things. 

• Domain: (-∞, ∞)  Range: [-∞, 4]

• Domain: [1, ∞)  Range: (-∞, 4]

• Domain: [-1. ∞) Range: [4, ∞) 

• Domain: [4, ∞) Range: [-1,∞) 

If the endpoint of the graphed square root is at (-3,-5), the domain is​ (a)   and the range is​ (b)
