Abaseball player hits a ball. the table represents a quadratic function that shows how the height of the ball changes over time.

what does the y-coordinate of the vertex represent?

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
