  15. Quadratic Functions Vocabulary Quadratic Function or The height in feet of a soccer ball t seconds after it is kicked into the air is modeled by the function above. Ordered pair

  16. Quadratic Functions Vocabulary Quadratic Function Parabola The shape of the graph of a quadratic function. The highest or lowest point on a parabola. Vertex Where the maximumor minimum value of a function can be found. Axis of symmetry The vertical line that splits the parabola in half. Roots / Zeroes / x-intercept The two points on the parabola that cross the x-axis. The value of “x” that makes the equations true when y = 0

  17. Quadratic Functions Vocabulary Quadratic Function Domain Set of all possible input values. x values Set of all possible output values. Range y values The graph shows the height h of a volley ball in meters, t seconds after it has been served.
