Exploring Multiple Representations of Functions

Which of the following is NOT a way to represent a relation?

• X and Y table

• Equation

• Graph

• Matrix

What does a point (-4, -4) on a graph indicate when using the equation y = 0.5x - 2?

• x = -4, y = 4

• x = -4, y = -4

• x = 4, y = -4

• x = 4, y = 4

Which equation corresponds to the verbal description 'y equals half of x minus 2'?

• y = 2 - 0.5x

• y = x/2 - 2

• y = 2x - 0.5

• y = 0.5x - 2

If a graph has the point (3, -1), what is the corresponding y-value when x = 3 in the equation y = 0.5x - 2?

• -1

• 1.5

• -1.5

• 0.5

How do you verify that a point belongs to a graph of a specific equation?

• By substituting the x-value in the equation

• By measuring the distance from the origin

• By changing the equation

• By drawing a new graph

How can a graph be converted into a set of ordered pairs?

• By changing the scale

• By drawing additional lines

• By listing the coordinates of existing points

• By plotting new points

What is the first step in converting a graph to an XY table?

• Choosing the scale

• Drawing the axes

• Identifying all the points

• Selecting the equation

Which ordered pair would be found in the set representation of the graph y = 0.5x - 2?

• (2, -1)

• (3, -0.5)

• (1, -1.5)

• (0, -2)

What is the result of graphing the point (2, 1) from a set?

• A point on the y-axis

• A point in the second quadrant

• A point in the first quadrant

• A point on the x-axis

What does the set notation {1, 3, 2, 1, 3, -1, 4, 2, 5, Z, 6, 6} represent in the context of graphing?

• A collection of graph titles

• A sequence of equations

• A set of ordered pairs

• A list of x-values
