Let A be the area under y = e and above the x-axis, on [0,a]. Let B be the area under y = e and above the x-axis, on [0,b]. B is 12.4 times A. What is b in terms of a? O a. b = In(12.4 + -11.40) O b. b = In(12.4e^a + -11.4000) O c. b = In(12.4e^a + 12.4) O d. a = In(12.4e^b + 1) O e. b = In(e^a + -10.40)
