Question

A quadratic function has a line of symmetry at x = –3.5 and a zero at –9. What is the distance from the given zero to the line of symmetry?

Answer 1

-3.5 to -9 is  a distance of 5.5

|-9-(-3.5)|=|-5.5|=5.5
the distance is 5.5

well it depends from where on the axis of symmetry

Answer 2

What is the other zero of the quadratic function?

Answer: 2
