Vocabulary

1. Maximum Value

1.1. Definition- Largest value of a function

1.2. Example-

2. Trinomials

2.1. Definition-math equation that has three terms which are connected by plus or minus notations

2.2. Example- 6x^2 +3x +5

3. Parabola

3.1. Definition- a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity ideally follows a curve of this shape.

3.2. Example-(x-2)^2 - 3

4. Standard Form

4.1. Definition-Math equation that has three terms which are connected by plus or minus notations

4.2. Example- 10^3=100

5. Imaginary Part

5.1. Definition - The coefficient b in a complex number a+ib, where i= square root of 1

5.2. Example- 5+2i

6. Absolute Value of a complex number

6.1. Definition-Distance between the origin and the point in the complex plane

6.2. Example- The difference between the origin,0, and the point, 8, is 8

7. Vertex of a parabola

7.1. Definition- Quadratic function of a parabola

7.2. Example- y= a(x-h)2-k

8. Imaginary Unit

8.1. Definition- An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit

8.2. Example-i^2=-1

9. Quadratic

9.1. Definition-envolving the second and no higher power of an unknown quantity or variable.

9.2. Example- 6x² + 11x - 35 = 0 2x² - 4x - 2 = 0 -4x² - 7x +12 = 0

10. Conjugate

10.1. Definition- Joined together.

10.2. Example- the conjugate of x + y is x - y. We can also say that x + y is a conjugate of x - y. In other words, the two binomials are conjugates of each other. (x + 4)(x - 4) = x^2 - 4x + 4x - 16 = x^2 - 16

11. Axis of Symmetry

11.1. Definition- line through the vertex of parabola that divides the parabola into two congruent halves

11.2. Examples- y=x2 -4x + 2 x=2

12. Zero of a Function

12.1. Definition- value of the input x that makes the output f(x) equal zero.

12.2. Example- its zeros are the - coordinates of the points where its graph meets the x-axis

13. Binomials

13.1. Definition-Quadratic expressions with two terms

13.2. Example-3x+5

14. Complex Conjugate

14.1. Definition- Each of the two complex numbers having their real parts identical and their imaginary parts of equal magnitude but opposite sign

14.2. Example- 3+ 4x is 3 - 4x

15. Imaginary Number

15.1. Definition-number expressed in terms of the square root of a negative number

15.2. Example- i^2=-1
