Movie expenditures, in billions of dollars, on advertising in a certain format from 1995 to 2004 can be approximated by f(t) = 0.04t + 0.33 if t ≤ 4 −0.01t + 1.5 if t > 4, where t is time in years since 1995. (a) Compute lim t→4− f(t). (If an answer does not exist, enter DNE.) Interpret the answer. Shortly 1999 (t = 4), annual advertising expenditures were close to $ billion. Compute lim t→4+ f(t). (If an answer does not exist, enter DNE.) Interpret the answer. Shortly 1999 (t = 4), annual advertising expenditures were close to $ billion. (b) Is the function f continuous at t = 4? YesNo What does the answer tell you about movie advertising expenditures? Movie advertising expenditures in 1999.
