E] D 'I. Part1 - Application Physics shows that when an object is thrown upward with an initial velocity ofvo, then its approximate height is given by this quadratic function. 5 = 4. 93:2 + 1rgt+ h A ball is thrown upward from the top of a building 15 meters high, at a \ elocitg.r of 2.3mfsec. Answer the following questions. Be sure to show and explain all work. a. Find the maximum height and the time in which it was attained (round to 3 decimal places) b. when does it reach the ground? (round to 3 decimal places) 0. Sketch a graph to illustrate your answers. 2. Part 2 - Find the error(s) and solve the problem correctly. Express the following in completed square form to find the vertex and the x-intercepts. f(x) = 3x3 + 12x + 7 Answer: Complete the square to find the vertex. 3(x2 + 12x) + 7 =0 3(x + 12x + 36) + 7 + 36 = 0 3(x + 6) +7+36=0 3(x + 6) +29 = 0 vertex = (-6, 29) Solve for x to get x-intercepts. 3(x + 6) = -29 29 (+6) = 3 29 (x + 6) =#1 3 29 63. Part 3 - Discussion Question A. Write out the equation for the Standard Form of a quadratic function and give an original example. B. Write out the equation for the General Form of a quadratic function and give an original example. C. Which form of a quadratic function is your preferred form? Explain your reasoning
