How can you find the maximum or minimum value of a quadratic function?Choose the correct answer below.O A. Find the y-intercept. The y-intercept is the minimum or maximum value depending on whether the graph opens upward or downward.OB. Find the vertex. The y-coordinate of the vertex is the minimum or maximum value depending on whether the graph opens upward or downward.O C. Evaluate the function with x = 0. The resulting y-value is the minimum or maximum value depending on whether the graph opens upward or downward.OD. Find the vertex. The x-coordinate of the vertex is the minimum or maximum value depending on whether the graph opens upward or downward.

Respuesta :

To find the maximum or minimum value of a quadratic function, we have to find its vertex since the curve of this type of function is a parabola.

Specifically, the y-value of the vertex is the minimum or maximum of the quadratic function. If the parabola opens up then the vertex is a minimum, if the parabola opens down then the vertex is a maximum.

Therefore, the right answer is B.
