I need help for this one too and it has graph

4. Expand (x-3)(x+2)(x+l)(x-1}. [-10] i . ...... x4-x3-7x2+x+6. Label its x and y-intercepts. What are its domain and range? 6. Solve xz-x-6=0. 7. What are the domain and range of: 1 '(x-2)(x+3)_4 y=2 8. The difference between life and death is often just minutes when it comes to stopping bleeding. Two emergency procedures are being compared for their speed in stopping bleeding at the scene of accidents. The time from when 911 was called to the time that paramedics reported the bleeding stopped was recorded for each procedure. The data is shown below (in minutes). Procedure A: '1', 6, 7, 4, 24, 8, 10, 3, 3, 5, 4, 17, 6, 5, 19, 29, 5, 6, 10, 4 Procedure B: 11, 13, 8, 9,12,10,10,9,12, '1', 10, 6,14,11,11 Make a histogram for each emergency procedure. You will need to choose an appropriate interval for each of the bins (\"bars") on your histogram. HINT: A very rough approximation of the number of bins your histogram should have is the square root of the number of values in the largest data set. Compare and contrast the two procedures. Which one would you recommend? Why
