Functions, Domain, and Range Mastery for Algebra 1

What defines a function in terms of inputs and outputs?

• Functions do not have inputs or outputs

• Each input can have multiple outputs

• Each output can have multiple inputs

• Each input has exactly one output

How can you determine if a graph represents a function?

• It passes the horizontal line test

• It passes the vertical line test

• It has repeating X values

• It has repeating Y values

What does the vertical line test determine?

• The range of a function

• The domain of a function

• If a set of points is a function

• If a graph is continuous

What is the result of evaluating F of 11 if f(x) = -3(x - 14)^2 + 3?

• -24

• 24

• -21

• 21

What is the correct function notation for replacing x with 11 in f(x) = -3(x - 14)^2 + 3?

• f(11) = -3(11 - 14)^2 + 3

• f(x) = -3(11 - 14) + 3

• f(x) = -3(11)^2 + 3

• f(11) = -3(x - 14)^2 + 3

How do you list the domain and range for a discrete relation?

• Listing out the values

• By drawing a graph

• Using inequalities

• Using integral values only

What is the domain of a function that includes all real numbers from -4 to 4, excluding 4?

• -4 < x ≤ 4

For a function with a domain of all real numbers except 4, how is this domain represented?

• x ≠ 4

• x > 4

• x < 4

• x = 4

Which scenario exemplifies causation?

• The temperature outside and the number of people at the park

• The number of cars in a lot and the day of the week

• The time a laptop is used and its battery charge

• The number of cookies sold and the number of milkshakes sold
