15 Quadratic Function terms

1. Parabola:The shape of the graph of a quadratic function also the set of points equidistant from a point,called the focus Ex:A football being thrown

2. Standard form of a linear equation:Ax+By=c,where A,B, and C are real numbers

3. Minimum Value:The y-value of the vertex when a parabola opens upward EX:

4. Maximum value:The y-value of the vertex when a parabola opens downward EX:

5. Binomial:A polynomial with two terms Ex:(x+5)(x-3)

6. Imaginary unit:The unit in the imaginary number system

7. Real part:For a complex number of the form a+bi, a is the real part

8. Complex conjugate:The complex conjugate of any complex number a+bi,denoted a+bi is A-Bi

9. Vertex:The vertex of a parabola is the highest or lowest point Ex:The highest you can throw something

10. Axis of Symmetry:The line that divides the parabola into two symmetrical halves Ex:Gridline

11. zero of a function:For the function, any number such that F(x)=0 EX:

12. Root of an equation:Any value of the variable that makes the equation true EX:

13. Trinomial: Polynomial with three terms Ex:(x+3)(x+4)(x-6)

14. Complex number:Any number that can be written as a+bi, where a b are real numbers

15. Imaginary part: For a complex number of the form a+bi,the real number b is called the imaginary part represented graphically as b units on the imaginary axis of a complex plane
