Find the difference quotient and simplify your answer A(t) 1 f(0) - ((9) = t # 10 t - 10 t - 9Determine the open intervals on which the function is increasing, decreasing. or constant. {Enter your answers using interval notation. If an answer does not exist. enter DNE.) x)=x39x2+2 increasing decreasing constant The distance s (in feet) a moving car is from a stoplight is given by the following function. s(t) = 10+3/2 Find the average speed of the car from t1 = 0 to tz = 9 seconds. ft per sec The average speed of the car from t1 = 4 to to = 9 seconds is 38 feet per second. Explain why the result is less than this value. O When to = 4, the maximum velocity of the car is higher. O When to = 4, the same total distance is covered in a short period of time. O The average speed of the car is not higher when t1 = 4. O When t, = 4, the minimum velocity of the car is higher. O When t, = 4, the total distance covered is higher
