(Critical Thinking) If K(x) = L(x) Then in your own words describe the effects that2L(3x – 1) +4 has on the graph of K(x)15. On April 6, 2009 an earthquake measuring 6.3 on the Richter scale devastated L'Aquila,Italy. The "world Series Quake" took place in San Francisco on October 17, 1989 andmeasured 6.9 on the Richter scale. How much more intense was the S.F. Quake of '89than that of the L'Aquila Quake in Italy?SF= logSoSL6.3 = logSo6.9 =and%3DHint: set up a subtraction equation

Modeling Human Height with a Logistic Function A male child is 21inches long at birth and grows to an adult height of 73inches. In this exercise, we make a logistic model of his height as a function of age. a. Use the given information to find K and b for the logistic model. b. Suppose he reaches 95 of his adult height at age 16. Use this information and that from part a to find r. Suggestion: You will need to use either the crossing-graphs method or some algebra involving the logarithm. c. Make a logistic model for his height H, in inches, as a function of his age t, in years. d. According to the logistic model, at what age is he growing the fastest? e. Is your answer to part d consistent with your knowledge of how humans grow?
