Document Summary

Unit #1 - transformation of functions, exponentials and logarithms. Some problems and solutions selected or adapted from hughes-hallett calculus. Note: this unit, being review of pre-calculus has substantially more practice problems than later units. Don"t be intimidated by the length, and just do as many problems as you need to refresh your skills. Functions: give the appropriate domain and range of the function. Setting the denominator equal to zero, we nd the x = 0 and x = 0. 75 make the denominator zero. The numerator must equal zero, so the solutions come from. 4 4x2 = 0 which gives x = 1 and x = 1 as solution. 1: let f (t) = t2 36, find all values of t for which f (t) is a real number, find the value(s) of t such that f (t) = 8. (a) the domain is ( , 6]u [6, ).
