Philip releases an arrow from a shoulder height of 4 ft. the arrow reaches a maximum height of 40 ft before it begins to fall. it lands on the ground about 160 ft away from where he is standing. Philip models this situation with a quadratic function. what is a zero of a function? what is the y intercept of the graph of the function? construct a rough graph of the situation based on your findings, where y represents the vertical height, in feet, and x represents the horizontal distance, in feet.
