Axis of Symmetry and Vertex of Quadratic FunctionsAuthor: Bennett Patricia
Description: (Calculator Active) Identify %22a%22, %22b%22, and %22c%22 of each quadratic function. You will have 6 minutes to find the axis of symmetry (x = - b/2a) and vertex of quadratic functions. Once you find the axis of symmetry (x), you will substitute the x-value into the function to find the y-value. The vertex is the x-value and y-value, (x, y).
The y-intercept is the value of %22c%22.
There are 6 questions. Your score will count as a grade.
