3. A special rocket is launched from the ground level. The trajectory of the rocket is a parabola. After 10 seconds, the rocket is 59 km above the ground, and after 30 seconds, the rocket is 171 km above the ground. a. Find the quadratic function that describes the position of the rocket above the ground Q km) with respect to the time from launching (measured in seconds). b. Find how long it takes the rocket to reach its maximum height. \f2. The graph below shows a multi-part function y : x), consisting of 3 line segments and half of a circle. All questions below refer to this function. a. Write the mum-gt rule for this function in terms of :3. Include corresponding domains. b. What is the range of this function? 0.
