Quadratic Functions (1)

1. discriminant - a function of the coefficients of a polynomial equation whose value gives information about the roots of the polynomial.

2. Minimun value - The minimum value of a function is the place where the graph has a vertex at its lowest point

3. Maximum value - Maximum, In mathematics, a point at which a function's value is greatest

4. Quadratic model - An equation that employs the variable x having the general form ax2 + bx + c = 0, where a, b, and c are constants and a does not equal zero; that is, the variable is squared but raised to no higher power.

5. Quadratic regression - regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:

6. Imaginary unit - The imaginary unit or unit imaginary number is a solution to the quadratic equation x² + 1 = 0

7. Complex plane - an infinite two-dimensional space representing the set of complex numbers, especially one in which Cartesian coordinates represent the real and imaginary parts of the complex numbers.

8. Standard form- is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

9. Quadratic Function - Quadratic Function-is a function that can be described by an equation of the form f=ax^2 + bx + c, where a ≠ 0.

10. Binomial - an algebraic expression of the sum or the difference of two terms.

11. parabola - A special curve, shaped like an arch

12. trinomial - consisting of three terms

13. Vertex form - a quadratic function is given by. f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola

14. imaginary part - a complex number. complex number, complex quantity

15. Imaginary number- expressed in terms of the square root of a negative number
