- Factored form
- Standard form
Explanation:
The three different forms of a quadratic function are:
- Expanded form
- Factored form
- Standard form
Expanded form, a sum of terms, each of which may be a product of a constant and some variables:
y=ax^2+bx+c
The parameter c is the y-intercept, while the parameter b is the slope and a determines the vertical stretching of the graph
Factored form, the product of a constant and two linear terms:
a.(x-p).(x-q)
The parameters p and q are the roots of the function and a determines the vertical stretching of the graph
Standard form, the sum of a constant term, k and a constant, a times the square of a linear term.
a.(x-h)^2+k
The vertex of the graph is located at the point (h, k) and a determines the vertical stretching of the graph...
