Introduction to Nonlinear Functions

Which function is nonlinear?

What makes a function nonlinear?

• It creates a straight line on a graph

• It has no variables

• It only has one term

• It has a variable in the denominator or exponent

Which type of function has a variable in the denominator?

• Rational

• Polynomial

• Exponential

• Linear

How does the graph of a linear function differ from a nonlinear function?

• Linear graphs are curved

• Nonlinear graphs are straight

• Linear graphs are straight lines

• Nonlinear graphs are always horizontal

• Quadratic

• Cubic or Polynomial

• Rational

• Exponential

• It grows at a constant rate

• It forms a straight line

• It stays the same

• It increases rapidly

Which table shows a nonlinear function based on rate of change?

• A table with no repeated values

• It has an exponent greater than 1

• It has no variable

• It's a line on the graph

• It only has one term

In which function does the rate of change vary?

How can you identify a rational function?

• It has no variables

• It has only constant terms

• It forms a straight line

• The variable is in the denominator
