Functions (general)

Two linear functions are shown below. Which function has the greater rate of change?

• Function A

• Function B

Who has won more tennis grand slam titles, Venus Williams or Serena Williams?

• Venus Williams

• Serena Williams

Two students write the equations below:

Sarah: y = 3x

Camille: y = x + 3

Mrs. Jeffery states that in Sarah’s equation, y is three times as much as x, and in Camille’s equation, y is _____________.

• 3 less than x

• 3 more than x

• 3 times as much as x

• the same as the value of x

_{H(2) < H(4). True or False?}

• True

• False; H(2) > H(4)

• False; H(2) = H(4)

Compare y = 0.5x - 6 to y = x

• y = 0.5x - 6 is flatter than y = x and below y = x

• y = 0.5x - 6 is steeper than y = x and below y = x

• y = 0.5x - 6 is flatter than y = x and above y = x

• y = 0.5x - 6 is steeper than y = x and above y = x

The cost of Nate’s movie rental service is described by the equation y = 4x + 6. The table shows the cost of Beth’s movie rental service. Whose rental rate is lower?
