7. Given the function f(.x) = |x|, write the equation of the function g whose graph is the graph of f translated 3 units to the left and 4 units down. Sketch the graph of the new function g. 9. Find the equation of the following sinusoid: 10. The following data comes from an experiment performed to determine if there is a relationship between the percentage of blood hemoglobin (H) in dogs and the number of red blood cells (C) they possess. Use a graphing calculator to find the equation of the line which best fits the data and gives the number of red blood cells (in millions per mm') as a function of the percentage of blood hemoglobin (C = mH + b). Also find the correlation coefficient for this scientific data and discuss whether or not the line is a good model for the data Blood hemoglobin % 93 99 96 80 98 Red blood cells 8.4 8.5 8.1 6.2 7.9 12. Write 4500 as a power whose base is e. 14. The graph of the function f(x) = Vx is shown on 15. Given: AD II BC the left. The graph on the right is the same graph DC II AB reflected in the y axis and translated 2 units to the right. Write the equation of the graph on the right. Write a two-column proof to prove: AD = BC -1/1 2 3
