3/27/2018 EPA 8 Do Now - Domain and Range from a Graph

All of the x values or inputs are called what?

• Domain
• Range

All of the y values or outputs are called what?

• Domain
• Range

What is the range of the graph?

• 1 ≤ x ≤ 5

• 1 < x < 5

• 1 ≤ y ≤ 5

• 1 < y < 5

What is the domain of the graph?
Remember:  Domain is x

• 1≤ x ≤ 4
• 1 < x < 4
• 1≤ y ≤ 4
• 1 < y < 4

What is the DOMAIN of this graph?

• -4 ≤ x ≤ 3

• -1 ≤ x ≤ 4

• 4 < x < 3

• -1 < x < 4

What is the domain?

• all numbers greater -10 and less than 10
• all real numbers
• all real numbers  greater than or equal to -10 and less than or equal to 10
• all real numbers greater than or equal to 0 and less than or equal to 10

What is the range?

An open circle means it DOES NOT equal that number so you must use < and >.

Only use ≤ and ≥ with a closed circle.

• -4 < x ≤ 5

• -4 ≤ x < 5

• -3 < y < 3

• -3 ≤ y ≤ 3

What is the range?

• -7≤x≤6
• -7<x<6
• -8<y<2
• -8≤y≤2

What is the range?

• -3 < y ≤ 3
• -4 ≤ y < 5
• -4 ≤ y ≤ 5
• -3 < y ≤ 3
