If a certain canon is fired from a height of 9.6 m above the ground at a certain angle the height of the cannonball above the ground h in meters at time t in seconds is found by the function h(t)=-4.9^2+27.5t+9.2 find the time it takes for the cannonball to strike the ground

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).
