Unformatted text preview: to find the y-intercept let x = 0. Graph using Method 2. f(x) = -2x 2-6x + 1 Find the vertex. Determine whether there is a maximum or minimum value and find that value. Find the range. Find the intervals on which the function is increasing and the intervals on which it is decreasing. Solve. p. 273, 44. A model rocket is launched with an initial velocity of 150 ft/sec from a height of 40 ft. The function s(t) = -16t 2 + 150t + 40 gives the height of the rocket t seconds after is has been launched. Determine the time at which the rocket reaches its maximum height and find the maximum height. p. 274, 49. Classic Furniture Concepts has determined that when x hundred wooden chairs are built, the average cost per chair is given by C(x) = 0.1x 2-0.7x + 1.625, where C(x) is in hundreds of dollars. How many chairs should be built in order to minimize the average cost per chair?...
