Alg2H: Domain and Range

What is the domain of the graph?

• -7 ≤ x < 5
• -3 ≤ x < 1
• -3 ≤ y < 1
• -7 ≤ y < 5

What is the range of the graph?

• -7 ≤ x < 5
• -3 ≤ x < 1
• -3 ≤ y < 1
• -7 ≤ y < 5

What is the domain?

• all real numbers
• 1<x<6
• {1,3,4,6}
• {-2,2,5}

What is the range?

• {-2,2,5}
• {1,3,5,6}
• all real numbers 
• -2<y<5

What is the range of the function? 

• y ≤ 2.5
• y > 2.5
• all real numbers

What is the domain of the function for this situation?

• 0<h<80
• 0≤h≤80
• 0≤t≤4.5
• 0<t<4.5

What is the range of the following graph?

• all real numbers
• all integers
• any real number greater than zero
• it can not be determined

• Function
• Not a Function

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values
• No, because the vertical line test shows there are repeating input values

What is the Domain?

• -3 < x ≤ 3

• -4 ≤ x < 5

• -4 ≤ y ≤ 5

• -3 < y ≤ 3
