A ball is thrown from the top row of seats in a stadium. The function h(t) = −16t2 + 128t + 50 gives the height, h, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground? Round your answer to the nearest whole number.

Is each relation a function? if so, state whether it is one-to-one or many-to-one. 3. (-4,7), (-3,5), (1,4), (3,-8), (5,-11) 4. (-4,8), (-2,4), (0,1), (2,4), (4,8) 5. (-2, 1), (-2,3), (0,-3), (1,4), (3,1)
