Study Notes
Vertex Form of a Parabola's Equation
- The vertex form of a parabola's equation can be written as y = a(x - h)^2 + k.
Representation of 'a' in Vertex Form
- The value of 'a' represents the vertical stretch factor, telling us how skinny or fat the parabola is.
Finding a Parabola's Equation Using Vertex Form
- To find the equation of a parabola using the vertex form, we need to know the vertex (h, k) and the value of 'a'.
Vertex of a Parabola
- The vertex of a parabola is the lowest or highest point on the graph, represented by (h, k), where 'h' is the x-coordinate and 'k' is the y-coordinate.
Purpose of Rewriting a Parabola's Equation in Vertex Form
- The purpose of rewriting a parabola's equation in vertex form is to easily identify the vertex, axis of symmetry, and direction of opening, making it easier to graph the parabola.
