Functions Representations

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values

• No, because the vertical line test shows there are repeating input values

Is the graph pictured a function?

• Yes

• No

• Function
• Not a Function

What is the definition of function?

• Has inputs and outputs

• Every input has only ONE output

• Inputs have different outputs every time

• x-values and y-values

Which equation matches the table?

• y = 3x + 9

Given the table, write the equation in the slope-intercept form.

• y = 1/3x + 6

• y = 3x + 6

• y = 2x + 6

• y = 1/2x + 6

What is the slope?

• -1/3

• -3

• -4

• 5

What is the equation for the table?
