Question

what is the axis of symmetry for the graph of a quadratic function whose zeros or -2 and 4?

Answer 1

Answer:

  x = 1

Step-by-step explanation:

As you might guess, the zeros are symmetrical about the axis of symmetry. That is, the axis of symmetry is midway between the zeros, so will be their average value:

  x = (-2 +4)/2 = 1

The axis of symmetry is x = 1.
