Nancy threw a ball upward from the roof of a 50-foot-high building at an initial velocity of 40 feet per second. The table shows the relationship between the time elapsed and the ball’s height above the ground. If the height of the ball is a quadratic function of time, between what times did the ball reach a height of 70 feet?

• Between 0 seconds and 0.5 seconds

• Between 1 seconds and 1.5 seconds

• Between 0.5 seconds and 1 second and between 1.5 seconds and 2 seconds

• Between 1 second and 1.5 seconds and between 1.5 seconds and 2 seconds
