16) Let x-4 x-2 x+2' G (x) = k, x = -2 Find the value of k so that lim G (x) = G(-2). x-2 17) Gary drives his car from San Francisco to Los Angeles, a total distance of 400 miles, leaving at 9:30 am and arriving at 2:15 pm the same day. What is his average speed, in miles/hour? 18) Does the parabola described by the function - f(x) = 2 (x+7) 4x - 9 (5 x) open upwards or downwards? 19) After jumping out of a plane at t = 0, a skydiver's altitude in the air in meters is given by the position function p (t) = -50t + 200t+2350, where t is the time in seconds. At what time will the parachuter be 100 meters from the ground? 16) Let x-4 x-2 x+2' G (x) = k, x = -2 Find the value of k so that lim G (x) = G(-2). x-2 17) Gary drives his car from San Francisco to Los Angeles, a total distance of 400 miles, leaving at 9:30 am and arriving at 2:15 pm the same day.
