A punter kicked a 41-yard punt. The path of the football can be modeled by y=−0.035x^2+1.4x+1, where x is the distance (in yards) the football is kicked and y is the height (in yards) the football is kicked.

1. Does the graph open up or down?

2. Does the graph have a maximum value or a minimum value?

3. Graph the quadratic function.

4. Find the maximum height of the football.

5. How would the maximum height be affected if the coefficients of the "x2" and "x" terms were increased or decreased?

Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster. which graph represents the set of heights that satisfy this requirement?

Which graph represents the same relation is the sa which graph represents the same relation as the set {(-3-2)}
