Linear versus non linear sub day 3/5

What defines a linear function?

• A function that can only be graphed as a curve

• A function that includes only negative numbers

• A function with a constant rate of change

• A function with a variable rate of change

How can you determine the rate of change from a table of values?

• Change in y over change in x

• By adding all the x-values together

• By dividing the sum of y-values by the sum of x-values

• Multiplying the first x-value with the first y-value

What does a straight line on a graph indicate about a function?

• The function has a variable rate of change

• The function is linear

• The function is undefined

• The function is non-linear

What exponent on the variable x indicates a linear equation?

• 0

• 2

• 1

• Any positive integer

If a graph has a curve, the function is considered:

• Linear

• Non-linear

• Constant

• Undefined

What is the rate of change if the change in y is 10 and the change in x is 2?

• 2

• 5

• 12

• 20

If a function's graph is made up of two straight line segments, it is:

• Dependent on the x-values

• Non-linear

• Undefined

• Always linear

A function with an exponent of 2 on the variable x is:

• Undefined

• Linear

• Non-linear

• Constant

If the rates of change in a table are 2 and 4, the function is:

• Linear

• Non-linear

• Constant

• Undefined
