Linear and Nonlinear Functions Identifying functions on tables, graphs, and equations. Irma Crespo 2010
Warm Up Graph y = 2x + 1 Rewrite the linear equation 3y + x = 9 to its slope-intercept form or the y = form. What is the linear equation for this graph?
Compare and Contrast Yards to Feet Number of Feet Number of Yards Yards to Square Yards Length of a Side of a Square Yard Area of Square (yd 2 )
Tables: Linear or Nonlinear linear nonlinear xy xy Is the rate of change constant (the same)?
Identify: Linear or Nonlinear Table? xy x0246 y02818 linear nonlinear
Graphs: Linear or Nonlinear Is the graph a straight line? linear nonlinear
Identify: Linear or Nonlinear Graph? linear nonlinear
Equations: Linear or Nonlinear REMEMBER: x 1 = x and x 0 = 1 In y = form, is x raised to a power of 1 or 0? Does x appear in the numerator? y = x + 4 y = 6/x y = 4 y = x y = ½ x linear nonlinear linear nonlinear linear
Identify:Linear or Nonlinear Equation? y = 2/x + 5y = x 2 + 8y =.6x 1 y = + 1 3x 2 linear nonlinear
Pointers to Keep in Mind A graph is linear if it is a straight line. A table is linear if the rate of change is constant. There is a common difference. An equation is linear if the power of x is either 1 or 0 and it appears in the numerator.
