FAQ

Q: What are quadratic functions?A: Quadratic functions are functions that can be represented by a quadratic equation in the form y = ax^2 + bx + c.

Q: What is the vertex of a quadratic function?A: The vertex is the highest or lowest point on the graph of a quadratic function. It can be found using the formula x = -b / (2a) and substituting this value into the equation to find the corresponding y-coordinate.

Q: How do you find the axis of symmetry of a quadratic function?A: The axis of symmetry is a vertical line that divides the graph of a quadratic function into two equal parts. It can be found using the formula x = -b / (2a).

Q: What is the discriminant of a quadratic function?A: The discriminant is a value calculated from the coefficients of a quadratic equation. It can be used to determine the number and type of solutions of the quadratic equation. The discriminant is calculated as b^2 - 4ac.

Q: How do you find the roots or zeros of a quadratic function?A: The roots or zeros of a quadratic function can be found by setting the equation equal to zero and solving for x. This can be done by factoring, completing the square, or using the quadratic formula.
