Functions and Vertical Line Tests Quiz

What is a function in terms of X and Y values?

• A relationship where each X value corresponds to multiple Y values.

• A relationship where each X value corresponds to exactly one Y value.

• A relationship where each Y value corresponds to multiple X values.

• A relationship where each Y value corresponds to exactly one X value.

Which table represents a function?

• A table where X values and Y values are the same.

• A table where Y values repeat.

• A table where no X values repeat.

• A table where an X value corresponds to two different Y values.

In a function, what must be true about the X values?

• X values must be greater than Y values.

• X values must be less than Y values.

• X values can repeat with different Y values.

• X values must not repeat with different Y values.

Which of the following sets of ordered pairs represents a function?

• {(1, 3), (1, 5), (3, 6), (4, 2)}

• {(1, 3), (2, 5), (3, 6), (4, 2)}

• {(1, 3), (2, 5), (2, 6), (4, 2)}

• {(1, 3), (2, 5), (3, 6), (3, 2)}

What is a quick way to determine if a set of ordered pairs is a function?

• Check if any Y values repeat.

• Check if any X values repeat.

• Check if the sum of X and Y values is constant.

• Check if the product of X and Y values is constant.

What is the domain of the function given the set of ordered pairs {(1, -4), (3, 2), (5, 7), (8, 1)}?

• {-4, 1, 2, 7}

• {-4, 2, 7, 1}

• {1, 3, 5, 8}

• {1, 2, 3, 4}

What is the range of the function given the set of ordered pairs {(1, -4), (3, 2), (5, 7), (8, 1)}?

• {1, 2, 3, 4}

• {-4, 1, 2, 7}

• {-4, 2, 7, 1}

• {1, 3, 5, 8}

• It includes all Y values.

Which of the following is true about the range of a function?

What does the vertical line test determine?

• If a graph represents a function.

• If a graph is quadratic.

• If a graph is symmetrical.

• If a graph is linear.
