Parabola |
A special cure, shaped like an arch. There is an AOS and a vertex in a parabola |
|
Quadratic Function |
An equation where the highest exponent of the variable (usually X) is squared. Ex. 2X2+5X+3 |
|
Factored Form |
Written as: F(x)= a(x-s)(x-t) You can find the zeros by subbing in the value of X to equal Zero. |
|
Standard Form |
Written as: F(x)= ax2+bx+c To find the zeros, you sub the A, B and C values into the discriminant. |
|
Vertex Form |
Written as: F(x)= a(x-h)2+k You can factor to find the zeros. The K-value is the Y-Intercept |
|
Maximum |
When the Parabola opens down (the A-value is negative) this is called a maximum. |
|
Minimum |
When the Parabola opens up (the A-value is positive) this is called a maximum. |
|
Vertex |
Where the parabola makes its sharpest turn. Consists of an X and Y coordinate |
|
Zeros of a Quadratic |
The solutions to the equation where the variable is equal to zero. |
|
X-Intercepts |
A point on the X-axis where a line passes through and Y is equal to zero. Ex. (12,0) (-3,0) (1,0) |
|
Y-Intercepts |
A point on the Y-axis where a line passes through and X is equal to zero. Ex. (0,4) (0,-14) (0,7) |
|
Complete the Square |
Complete the square when going from standard form to vertex form. This helps to find the vertex of an equation. |
|
Radical |
The symbol that means "root of". |
