The "x" column represents:

• Inputs

• Outputs

• Functions

• Relations

The "y" column represents:

• Inputs

• Outputs

• Functions

• Relations

Is this a function?

• Yes

• No

Is the relation linear?

• Yes

• No

The first input given for the function is -5. How would you find the output?

• y = 2(-5) - 6

• (-5) = 2x - 6

• y = 2(-5)

• y = -5 - 6

The first input given for the function is -10. How would you find the output?

• y = -10^4

• y = -10

• y = (-10)(4)

• y = (-10)^4

A relation is:

• The set of x-coordinates

• The set of y-coordinates

• A set of ordered pairs

• A formula

In math, "determine" means:

• Solve

• Decide

• Simplify

• Evaluate

Linear functions are -or- could be written in the form (select all that apply):

• y = mx + b

• y = x^2

• slope-intercept form

• x = 10/y
