Function Linear

The table shown is:

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

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

• Not a function, because 1 appears in the table twice.

• A function but non linear, because it doesn't start at zero.

The table shown is:
(hint: find the rate of change)

• proportional function.

• linear function.

• non linear function.

• Not a function.

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:

• linear function but not proportional.

• function, but not linear or proportional.

• proportional function.

• Not a function, linear or proportional.

The diagram shows a linear function of g. What is the value of k.

• 5

• 4

• 7

• 8

A holiday meal costs $12.50 a person plus a delivery fee of $30.

• 30 + 12.5x 

• 12.5 + 30

• 12.5 + 30x

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:

• Proportional because it goes through the origin.

• Linear, because there is a pattern.

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

• All of the above.

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.
