4 Using transformations to graph logarithmic functions. Graph f(x) = log ½ x What are three points on the graph? Describe in words the transformations needed to graph and sketch on graph paper. a. y = f (x+2) b. y = -f(x) -1 c. y = 2 log ½ x + 3 d. y = 1- log ½ (x-2)

At the end of the last lecture, and every month for the next year, the students were tested to see how much they remembered from the lectures. The average scores were given by • What was the average score after 2 months? • What was the average score after 6 months? 12 ), 1 ln( 6 75 ) ( ≤ ≤ +-= t t t f...
