Curve Fitting and the TI-85 calculator 6.0 Students add, subtract, multiply, and divide complex numbers. 7.0 Students add, subtract, multiply, divide, reduce, and evaluate rational expressions with monomial and polynomial denominators and simplify complicated rational expressions, including those with negative exponents in the denominator. 8.0 Students solve and graph quadratic equations by factoring, completing the square, or using the quadratic formula. Students apply these techniques in solving word problems. They also solve quadratic equations in the complex number system.
Students graph quadratic functions and determine the maxima, minima, and zeros of the function.
11.1 Students understand the inverse relationship between exponents and logarithms and use this relationship to solve problems involving logarithms and exponents. Students judge the validity of an argument according to whether the properties of real numbers, exponents, and logarithms have been applied correctly at each step. 12.0 Students know the laws of fractional exponents, understand exponential functions, and use these functions in problems involving exponential growth and decay. 13.0 Students use the definition of logarithms to translate between logarithms in any base. Students understand and use the properties of logarithms to simplify logarithmic numeric expressions and to identify their approximate values.
