FAQs on Quadratic Equation: Maxima & Minima Video Lecture - General Test Preparation for CUET - CUET Commerce

1. What is the formula to find the maximum or minimum value of a quadratic equation?
Ans. The formula to find the maximum or minimum value of a quadratic equation in the form ax^2 + bx + c is given by -b/2a. This value represents the x-coordinate of the vertex of the parabola.
2. How can I determine if the quadratic equation has a maximum or minimum value?
Ans. The nature of the maximum or minimum value of a quadratic equation can be determined by observing the coefficient of the squared term (a). If a is positive, the parabola opens upwards, indicating a minimum value. If a is negative, the parabola opens downwards, indicating a maximum value.
3. Can a quadratic equation have both a maximum and a minimum value?
Ans. No, a quadratic equation can have either a maximum or a minimum value, depending on the nature of the parabola. The parabola can only have one extreme point, which represents either the maximum or minimum value.
4. How can I find the coordinates of the maximum or minimum point of a quadratic equation?
Ans. To find the coordinates of the maximum or minimum point of a quadratic equation, substitute the x-coordinate of the vertex (obtained using the formula -b/2a) into the equation. This will give you the y-coordinate of the vertex.
5. Is the maximum or minimum point of a quadratic equation always located on the x-axis?
Ans. No, the maximum or minimum point of a quadratic equation is not always located on the x-axis. It can be above or below the x-axis, depending on the nature of the parabola. If the parabola opens upwards, the minimum point will be above the x-axis, and if it opens downwards, the maximum point will be below the x-axis.
