3. Zoe likes to make pancakes. She can flip a pancake in the air and have it land in the frying pan. The
motion of the pancake is represented by the equation y = -9x² + 9.8x, where x represents the number of
seconds after Zoe flips the pancake in the air, and y represents how high the pancake is above the pan.
How long is the pancake in the air? Algebraically, how can you tell?
a.
b.
At what time does the pancake stop going up and start coming down? Prove it algebraically.
C.
How high is the pancake at the top of its flight? Prove it algebraically.
