In Exercises 1-4, find formulas for the functions / + 8. J - g. and f g. Give the domain of each. 1. f(x) = 2x - 1; g(x) = x2 2. f(x) = (x - 1)2: 8(x) = 3 - x 3. f(x) = Vr. g(x) = sinx 4. f(x) = Vx + 5: 8(x) = 1x+ 31 In Exercises 5-8, find formulas for f/g and g/f. Give the domaity of each. 5. f(x) = Vx + 3: g(x) = x2 6. f(x) = Vx - 2; 8(x) = Vx+4 7. f(x) = x2, g(x) = VI - x 8. f(x) = x3: 8(x) = VI -x3 9. f(x) = x3 and g(x) = 1/x are shown below in the viewing window [0. 5] by [0, 5]. Sketch the graph of the sum (f + g)(x) by adding the y-coordinates directly from the graphs. Then graph the sum on your calculator and see how close you came. [0, 5) by [0, 5] 10. The graphs of f(x) = x3 and g(x) = 4 - 3x are shown in the viewing window [-5, 5] by [-10. 25]. Sketch the graph of the difference (f - g)(x) by subtracting the y-coordinates directly from the graphs. Then graph the difference on your calculator and see how close you came
