If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. Tutorial Exercise For what value of the constant c is the function f continuous on (-co, co)? f ( x ) = 3 cx2 + 3x if x 0 h = "m 4.9(a2 + Zah + h2 a2) h > 0 h . 4.9( ) = lim h - U h = lim 4.9( ) h a U ll (b) Since the observation deck is 400 m above the ground, the ball will hit the ground at the time t1 when s(t1) = 400, that is, 4.9} = 400. This gives the following. (Round your approximation to one decimal place.) ('12 = t1 = 400 4.9 and 400 4.9 The velocity of the ball as it hits the ground is the following.
