Problem 6

Square Root and Quadratic Function Problem: Let f and g be defined by where the values of x make f(x) a real number g(x) = x2 4 where x is any real number a. Plot the graphs of f, g, and f g on the same screen. Use a friendly x-window of about 10 x 10 that includes the integers as grid points. Sketch the result. b. Find the domain of f g . Explain why the domain of f g has positive and negative numbers, whereas the domain of f has only positive numbers. c. Show algebraically that f(g(4)) is defined, but f(g(1)) is undefined. d. Show algebraically that g(f(6)) is defined, but g(f(3)) is undefined. e. Plot the graph of g f. Make sure that the window has negative and positive y-values. f. The graph of g f appears to be a straight line. By finding an equation for g(f(x)) explicitly in terms of x, determine whether this is true.

Allan John Bio Study Guide 1. Define Chromosome: Answer: double­stranded molecule of DNA wound around nucleosomes 2. Define and describe the 2 phases of the Cell Cycle. Answer: The 2 phases are the Interphase and the Mitotic Phase. The Interphase is the growth of the cell. A cell spends 90% of its life in this phase. The Mitotic Phase is where Cell division occurs. 3. Describe what happens and the functions of the following parts of the Interphase a. G1 – The growth and normal functions happen here such as; muscle cell contraction and the making of organelles. b. S – synthesis of DNA, Chromosomes are duplicated and ready for cell division c. G2 – continued growth and preparation for cell divisio
