The total sales of a company (in millions of dollars) t months from now are given by the following formula. S(t) = 5 ft + 1 (A) Use the four-step process to nd S'(t). (B) Find 8(15) and S'(15). (C) Use the results in part (B) to estimate the total sales after 16 months and 17 months. (A) S'(t)= |:| (B) 8(15) = (Type an integer or a decimal.) S'(15)= 1 (Type an integer or a decimal) (C) 3(16) x (Type an integer or a decimal) 8(17) z :| (Type an integer or a decimal.) x + 5 Determine where the function m(x) = is continuous. (x 5)(x 2) The function is continuous on D. (Simplify your answer Type your answer in interval notation.) Use the graph of the function fshown to the right to estimate the indicated function values and limits. Complete parts (A) through (E). E> (A) Find the value of lim f(x). Select the correct choice below and, if necessary, ll in the answer box to complete your choice. x-> - 2' C: A. lim f(x) = xv -2' C? B. The limit does not exist. (B) Find the value of lim x). Select the correct choice below and, if necessary, ll in the answer box to complete your choice. xr - 2 C? A. lim f(x)= xrT C3 B. The limit does not exist. (C) Find the value of lim 2f(>
