Presentation Transcript

  1. 10.8 Identify Linear, Quadratic, and Exponential Functions Distinguish quadratic and exponential functions as nonlinear using a graph and/or a table of values. Distinguish between the equations of linear, quadratic, and exponential functions (e.g. function families such as y=x2, y=2x, and y=2x).

  2. Linear Functions Y Is this function linear? y = x + 2 X

  3. Quadratic Functions Y y = x2 + 1 X

  4. Exponential Functions Y y = 2x X

  5. Comparing Functions • Figuring out which it type of function it is is fairly easy from the function and/or the graph, but when you have just the table of values it becomes a little harder.

  6. Linear, Quadratic, or Exponential?

  7. Linear, Quadratic, or Exponential?

  8. Linear, Quadratic, or Exponential?

  9. Writing the equation from the table. • To write the equation first Identify the function and then use the proper formula to help you write it. • Linear y=mx+b

  10. Writing the equation from the table If Exponential use Where x and y come from the table and b is the pattern found.

  11. Writing the equation from the table • Quadratic use Where x and y come from the table.

  12. More Practice • Classwork/Homework
