Problem #1. The graph of a function y = f (x) is shown below. Each square is one—by
one unit. ' Math 110 Lab 1 FS 2008 a) State the Domain and Range of f. Df R b) Write a sequence of transformations that leads from f to g(x) = —% f (—x) + 4 . Provide details of each transformation. 0) Use the sequence in b) to show changes in the Domain and Range and
state Dg and Rg. d) Sketch the graph of g(x) = ——;— f (—x) + 4. Use different colors to show all intermediate graphs. e) Point (4, 0) is on the graph of f. Which point corresponds with (4, O)
on the graph of g? (4, O) —~> . Math 110 Lab 1 FS 2008 Problem #2. In a study of the factors that affect success in a calculus course, data were
collected for 15 different people. Scores on an algebra placement test are
