Transcription

1 Honors Algebra II Final Exam Order - Fall 2018 For the Final Exam for Algebra II, students will be given the opportunity to re-take any of their Fall 2018 Assessments. To do so they will need to place an order for the assessments they want to retake so that their individualized final exam can be prepared. Students grades will not be lowered if they earn a grade lower than their original assessment grade. Students Current Overall %: Current Letter Grade: # Topic Current Score ReDo YES Required if score is less than 18 Ex This is an example of how 20/25 to fill out this sheet x 20 Simplifying complex numbers (i) ReDo - NO 21 Add, Subtract and Multiply Complex Numbers 22 Finding zeros, completing the square 23 Solving quadratic equations and using the quadratic formula 50 Finding zeros, writing a polynomial function from zeros, using synthetic division 51 Graphing Polynomials 52 Add, Subtract and Multiply Polynomials 53 Use pascals triangle to expand a binomial. 80** Solve systems of equations in two variables 81** Solve absolute value equations and solve multivariable equations 82 Find the vertex, find the axis of symmetry and graph a parabola 83 Graph polynomial equations on coordinate axes with labels and scales 84 Find the center, radius and diameter of a circle. Graph the circle. **To improve your grade on Test 1 (from Mr. Ben Rudy s time as the substitute) you will sign up to take #80 AND #81 and your grade will be averaged. If you do not plan to re-take any of the assessments for the final exam, you must complete the attached Final Exam Review packet AND return this paper, signed by your parent/guardian no later than Thursday, December 13 th at 1pm indicating that they approve of your current Algebra II course grade and will not require you to re-do any assessments.
