Does the mapping diagram represent y as a function of x?

• Function, because each X value produces exactly one Y value.

• Not a Function, because each X value does not produce exactly one Y value.

• Not a Function, because each x value produces exactly one value.

• Function, because each X value does not produce exactly one Y value.

Does the graph represent y as a function of x?

• Function

• Not a Function

Does the table represent y as a function of x?

• Yes, it is a function because each input has one output.

• No, it is not a function because the y value 6 is repeated.

• Yes, it is a function because each output has one input

• No, it is not a function because it would not pass the vertical line test.

Write an equation in slope intercept form for the line that passes through the points (1, 2) and (-2, 5)

and has a y intercept at (0, 3)

• y=x+3

• y=-x+3

• y=-x+1

• y=3x+3

What are the slope and y-intercept of the graph of the linear function shown on the grid?

• Slope = 4, y-intercept = -6

• Slope = -4, y-intercept = -1.5

• Slope = -1/4, y-intercept = -1.5
