The quadratic function f(x) has one zero at x=-5 and a turning point at (3,10). What is the value of its other zero?

hope that helps

The easiest way to find the turning point is when the quadratic is in turning point form (y = a(x - h)2 + k), where (h, k) is the turning point. To get a quadratic into turning point form you need to complete the square.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
