Precalculus Unit 2
Polynomial Functions

Learning Targets

  • Graph a quadratic function, finding the vertex (formula method and completing the square method), x-intercepts and y-intercept.
  • Use long division and synthetic division to divide polynomials by other polynomials.
  • Perform operations with complex numbers and plot complex numbers in the number plane.
  • Graph polynomial functions by finding the x-intercepts and y-intercepts, including double and triple roots.
  • Determine the number of rational and real zeros of polynomial functions, and find them.
  • Write a polynomial equation given its roots. Know and apply the Fundamental Theorem of Algebra. Apply ponynomial functions to model and solve problems.
Use a polynomial function to model and solve a real-life problem.
