Evaluate a nonlinear function

Evaluate a nonlinear function

What you'll learn

  • Given a nonlinear function in equation form and a set of x-values, students will accurately evaluate the function for each x-value and determine the corresponding y-values with 80% accuracy.
  • Students will be able to identify whether a given function represented graphically or algebraically is linear or nonlinear, justifying their classification using mathematical reasoning in at least 2 out of 3 examples.
  • Students will be able to explain, in their own words, why substituting different x-values into a nonlinear function results in different y-values, demonstrating understanding by providing at least two distinct examples.
  • Students will be able to apply their understanding of nonlinear functions to solve real-world problems, such as calculating the area of a circle given its radius, presenting the solution with correct units and justification in at least 1 out of 2 scenarios.
