6 Question 8 5 Refer to the figure. The graphs of f(x)-2x² - 4x + 30 and g(x) = 2x+10 are drawn (not to scale). 1 .1 A and B are the x-intercept and D is the y-intercept of f(x). G is the turning point of f(x). A is the x-intercept and D is the y-intercept of g(x). Use the sketch to answer the following question. Determine the coordinates of A, B, C and D. 2 Hence, write down the values of x for which f(x)> 0. 3 Determine the coordinates of E, one of the points of intersection of f(x) and g(x). (4) 4 Determine the equation of the axis of symmetry of f(x). (2) 5 Determine the length of GH if GH is parallel to the y-axis. (5) If JL-60 units, determine the length of Help Atst n (5) •Part of origan [26]
