Question

If a quadratic function has an axis of symmetry of x = 2 and a zero of-1. Which of the

following is the other zero?

Answer 1

The line of symmetry is the center/ middle of the parabola where the curve shifts. Since the line of symmetry is at x=2 and the zero is at x= -1, you have the find the difference between the values which is 3. So the other zero is three the right of the line of symmetry at x= 5.
