Finding max and min of a quadratic function
WebThe minimum of a quadratic function occurs at x = − b 2a x = - b 2 a. If a a is positive, the minimum value of the function is f (− b 2a) f ( - b 2 a). f min f min x = ax2 + bx+c x = a x 2 + b x + c occurs at x = − b 2a x = - b 2 a Find the value of x = − b 2a x = - b 2 a. Tap for more steps... x = 5 2 x = 5 2 Evaluate f (5 2) f ( 5 2). WebIn many quadratic max/min problems, you'll be given the formula you need to use. Don't try to figure out where they got it from. Just find the vertex. Then interpret the variables to figure out which number from the vertex you need, where, and with what units. Your factory produces lemon-scented widgets.
