A dolphin is jumping out of the water. The function f(t)=-15t²+20t models the height in feet after t seconds of the dolphin. What do the coordinates of both x-intercepts represent in context of the dolphin? The x-intercepts coordinates represent the highest height and time it took for the dolphin to jump up and back down. The coordinates of the x-intercepts are the starting time/height and ending time/height of the dolphin's jump. O The coordinates of the x-intercepts are the axis of symmetry of the dolphin's path
