Write the vertex form of a quadratic equation for the graph.
Write the vertex form of a quadratic equation for the graph.
Identify the transformation (stretch, compression, reflection, translation) of the graph of the parent function
that results in the graph of the function g.
Graph the quadratic function by using a table of values. Identify how the graph is related to the graph of the parent quadratic function. Identify the axis of symmetry and the vertex.

Molly is practicing kicking a soccer ball. She kicks the ball with an initial vertical velocity of 40 feet per second and at a height of 2.5 feet.
A. What quadratic function, in standard form, models the height of the soccer ball?
B. What is the maximum height of the soccer ball?
C. After how many seconds does the soccer ball reach its maximum height?
The height, in feet, of an object at time t, in seconds, after it is launched into the air can be represented by the functions below.
A. Which function would you use to find the maximum height reached by the object? What is the maximum height?
B. Which function would you use to find the time the object is in the air? How long is the object in the air?
