Tap for more steps... The maximum or minimum of a quadratic function occurs at x=âb2ax=-b2a. If aa is negative, the maximum value of the function is f(âb2a)f-b2a. If aa is positive, the minimum value of the function is f(âb2a)f-b2a. fminfmin(x)=ax2+bx+cx=ax2+bx+c occurs at x=âb2ax=-b2a. Find the value of xx equal to âb2a-b2a.
