Multiple Choice

• Diagram A

• Diagram B

• Diagram C

• Diagram D

Multiple Choice

• Yes, every input only has one output

• No, an input has more than one output

Multiple Choice

• This graph is ONLY a relation because one input has more than one output.

• This graph is a relation AND a function because each input only has one output.

Multiple Choice

• YES

• NO

Multiple Choice

• linear, same rate of change in x's and y's

• nonlinear, different rate of change in x's or y's

Multiple Choice

• nonlinear, NOT straight line

• linear, straight line!

Multiple Select

• Equation 1 (left) is linear because it can be arranged in y=mx+b form

• Equation 1 (left) is nonlinear because it is not in y=mx+b form

• Equation 2 (right) is linear because it can be can be arranged in y=mx+b form

• Equation 2 (right) is nonlinear because it is not in y=mx+b form and has an exponent
