Question 1. Areas of Strength This was a well done question. Students could find the zeros of a function using the calculate menu on their graphers. Windows were adjusted properly to show the minimum point. Areas of Weakness Some students gave only the zeros and not the inequality regions. There were many inequalities that were expressed incorrectly. (reversed signs, no equal signs, combining the separate regions into a single compound statement, etc.). Students entering separate functions often did not show the intersection points in their sketches. Some answers were expressed as ordered pairs. Other errors included extra information in the answer box, and there were some sign errors when equating the function to zero. 2. This was a well done question. Students correctly set up a linear- quadratic system and solved it by substitution. The squaring of a binomial was well done. 3. This was a well done question. Students demonstrated good knowledge of the growth formula, and used logs effectively to solve the equation. A few students could not derive an equation involving the perimeter of a triangle. x^2 + y^2 = 25 was a common error, and x^2 + x^2 often became x^4 instead of 2x^2. The largest single error was incorrect rounding. Occasionally, the base was given as (1+2) or (1+0.5), and the exponent of t/20 became 20/t. Principles of Mathematics 12 Examination -3- April 2001 Report to Schools 4. Students recognized that the locus was a parabola. There was good use of the distance formula although markers did report a variety of successful methods. As in question #2, the squaring of a binomial was well done. Ther...
