Domain and Range Practice

The graph of quadratic function f is shown on the grid. Which of these best represents the range of f?

• All real numbers less than -8 or greater than 0.

• All real numbers

What is the range of the graph?

• [-7, 5)

• (-3, 5]

• [-3, 1)

• (-7, 5]

What is the domain?

• [-2, 3]

• [-2, 3)

• (-2, 3]

• [-3, 4]

• (-3, 4]

What is the domain?

• None of the answer choices

What is the domain?

• (-3 , 3)
• [-4, 5]
• (-4, 5)
• (-3, 3]

What is the range of the graph?

• (-∞,∞)
• [-1,0]
• [-1,3]
• [3,∞)

What is the range of the graph?

• (-∞,∞)
• [0,∞)
• (0,5)
• [-1,∞)

What is the definition of function?

• Has inputs and outputs
• Every input has only ONE output
• Inputs have different outputs every time
• x-values and y-values

Does this mapping diagram represent a function?

• No, because an input value goes to multiple output values
• Yes, because each input goes to one and only one output

Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)
• (3,4) (4,-3) (7,4) (3, 8)
• (6,-5) (7, -3) (8, -1) (9, 1)
• (2, -2) (5, 9) (5, -7) (1, 4)
