What is the Maximum of a Quadratic Function?

What is the Maximum of a Quadratic Function?

Summary

  1. If the graph has an upside-down U shape, that means it has a negative value for 'a', the coefficient in front of the x2 term
  2. The maximum value of a quadratic is also the vertex

Notes

    1. Quadratic functions have either maximums or minimums, not both
    1. You can only have maxima on graphs with upside-down U shapes
    2. Graphs with upward-facing U shapes will have a minimum instead of a maximum
