Domain and Range of Parent Functions

What is the range?

• y≥-3

• y≥-1

• All real numbers

• y≤-1

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.

DOMAIN?

• (-∞,∞)

• [0,∞)

• (-∞,0]

• -2, 2

RANGE?

• (-∞,∞)

• [0,∞)

What is the range of 2^x?

• All real numbers

• (0,∞)

What is the domain of the Cubic Parent Function?

• [0,∞)

• (0,∞)

• (-∞,∞)

What is the range of the Absolute Value Parent Function?

• All Real Numbers

• (0,∞)

• [0,∞)

• (∞,0]

What is the range?
Remember range is the "y" values (up and down) 
And an open circle means it DOES NOT equal that number - use < and >
Only use ≤ and ≥ with a closed circle. 

• -4 < x ≤ 5

• -4 ≤ x < 5
