Function or Not Linear Tables

Is the graph pictured a linear or nonlinear function?

• Linear

• Nonlinear

Which graph(s) show nonlinear functions?

• Graph I, only

• Graph II, only

• Graph I and Graph II, only.

• Graph I, Graph II, and Graph III

Which equation matches the table?

• y = 3x + 9

• y = x + 9 

• y = x + 3

• y = 12x - 3

Is the table linear or non-linear?

• Linear

• Non-Linear

Is the table linear or non-linear?

• Linear

• Non-Linear

The mapping shown is:

• Not a function because there are more y's than x's.

• Not a function because  the x-value of 5 goes to multiple y values.

• A function because all of the x values are different.

• A function because all of the y values are different.

The graph shown is:

• A linear function but non proportional

• Not a function because it is not a straight line.

• Proportional because it goes through the origin.

• A function but not linear or proportional.

The mapping shown is:

• Not a function, because there are letters.

• Not a function, because two different numbers go to C.

• A function, because none of the x values go to more than one y value.

• A function, because the numbers are in order.

The table shown is:

• Linear, because it is going up by 2 each time.

• Proportional, because 1 goes evenly into 4 and 2 goes evenly into 6.

• A function, because none of the x values are repeated.

• Not a function because it doesn't start at zero.

Mary buys concert tickets for $45 each plus a service fee of $15 for the order. This situation is:

• Proportional, because you can figure out the total cost.

• Linear, because all of the tickets are the same price, but non proportional because you add the service fee

• Not a function, because you have to pay a service fee.

• A function but non linear because each ticket costs more than the fee.
