What are the different forms of a quadratic function and what do the variables represent?

The three different forms of a quadratic function are:

Step-by-step explanation:

The three different forms of a quadratic function are:

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...
