Math Vocabulary

2. a fixed value in an equation
3. Number A number written in the form a + bi, where a is a real number and bi is an imaginary number.
5. Form y=a(x-p)(x-q)
7. Number The complex number whose square is -1.
10. The point on a graph that intersects with the x-axis. It's the point where f(x) = 0.
11. The value of the expression b^ - 4ac, which tells how many and what type of solutions a quadratic equation has.
14. the point of intersection of lines or the point opposite the base of a figure
15. method of solving a quadratic equation by looking for the multiplication factors of the equation
18. the largest exponent in an equation; the x2 makes an equation a quadratic equation (or "second degree"), while x3 would make an equation a cubic equation (or "third degree")

1. Function the most basic function of a family of functions, or the original function before a transformation is applied
3. The number that multiplies the variable by a specific amount (the 4 in 4x)
4. Value The lowest point of a parabola (when a>0)
6. Function a function that can be written in the form f(x)=ax^2+bx+c, where a, b & c are real numbers and a is not equal to zero
8. Of Symmetry A line that divides a figure in half so that each half is the mirror image of the other
9. Form A quadratic function written in the form f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola.
12. number numbers that have a positive result when multiplied by itself (as opposed to an imaginary number, which has a negative result [√(−1)]
13. Value The highest point of a parabola ( when a<0)
14. the letter in a mathematical expression that represents an unknown value (usually what you solve for)
16. a plane curve formed by the intersection of a right circular cone and a plane parallel to an element of the curve
17. Form A quadratic function written in the form f(x) = ax² + bx + c.
