Document Summary
Example 1. 1: suppose that you are planning to buy apples and their cost is . 47 per pound (. 14/kg) in your local shop. A function f is a rule or process that assigns to each input a corresponding output. Example 1. 2: find the domain and the range for the following functions. 1: f(x) = x2 2) f(x) = x3 3) f(x) = x. Find range of f(x) = x2, dom f = [-1, 2]. P(x) = anxn + + a2x2 + a1x + a0 where ai, i = 1, 2, , n, are constant. Quadratic function: p(x) = ax2 + bx + c. Q x f x where p and q are polynomials and q is not the zero polynomial. f x. Example 1. 6: to reduce inventory, a department store charges three rates. If a customer buys 0-5 pairs of socks, the price is . 50 per pair. If a customer buys 6-10 pairs of socks, the price is . 00 per pair.
