Document Summary

Math 203 - calculus 1 lecture 1: review. What is a function? f is a rule that assigns to each element x in a set d exactly one element called f(x). The range is all possible values of f(x) or y. v review example given in class: You are given a rectangular box (with no top) Volume = 9 cm3 > square base x = length of the base f(x) = surface of the rectangle. To find f(x) first you have to find the volume. However, we want to express everything in x. Domain = all real numbers or: what is the domain of = To see if a rational function is defined x 0 so. In the case of a square root or radical function, x is defined when the numbers are positive. Thus, domain = all real numbers x + 2 0 x -2. D = (- , 0) u (0,1) u (1, +) v review example:
