Unformatted text preview: ECON 1078 - Mathematical Tools for Economists Midterm 2 Review Chapters 4.6-4.10 4.6 Quadratic Functions • Know how to find the maximum and minimum of a quadratic function. Remember that the max/min will be at x =- b 2 a • Practice problems: 4.6.3, 4.6.8 and long problem on practice exam. 4.7 Polynomials • We have mostly emphasized how to factor polynomials and how the zeros of a polyno- mials are linked to the factors. If x = a is a zero of a polynomial then ( x- a ) is a factor of that same polynomial. We can use polynomial division to factor the polynomial. • Know how to find the equation of polynomial given the graph of the same polynomial (example 4 p. 108). • Practice problems: 4.7.3, 4.7.4 and long problem on practice exam. 4.8 Power Functions • Recognize a power function, and know how to solve simple power function equations without using the natural log. • Practice problems: 4.8.3, multiple choice problem on practice exam....
