Question

How can you find the maximum or minimum value of the quadratic function?

A. Evaluate the function for x = 0. The resulting value is the maximum or the minimum value.
B. Find the vertex. The y-coordinate of the vertex is the minimum or the maximum value of the parabola.
C. Find the y-intercept. The y-intercept is the maximum or the minimum value of the parabola.
D. Find the vertex. The x-coordinate of the vertex is the minimum or the maximum value of the parabola​

Answer 1

If the eqn is negative then it will be a maximum value but when the eqn is positive the curve will be a minimum curve

Answer 2

B

Explanation:

the y-coordinate of the vertex will be the max or min value of the quadratic function

hope this helps!
