(a) For matrix A = (" ), ifg(X) = X² + 4x + 2, what is the answer to g(A)? (b) Using algebra, find the solution to the system of inequalities below y< 5- 3x y + 19 2 x² – 8x (c) What is peculiar about the slope of a function before and after a point of inflection as compared with the slope before or after a maximum or minimum point? (d) Suppose that the satifaction received from a number of rides taken on a roller coaster 0.5 is given by the function S(x) = 200| , where S is the satisfaction received and x is the number of rides taken. (1) Find the rate at which the satisfaction changes with respect to the number of rides taken.
