# How to arrange a function quadratics of the graph

|At this time I would give a tutorial and the way how to make a graph of graphic function. This tutorial i ensure will give the best solution for student learning mathematics.

Okey lets we do.

This is the formulas needed to make equation quadratic function.

**Case 1 **

If the graph sketch through the vertex /extreme (p , q) and any point (x , y). The graph like this

we get the formulas :

**Case 2**

When the graph of function across X axis we say , and through any point then we use this formula :

we get the formula :

Lets we see the examples below.

**Example 1**

Identify the graph function of quadratic equation of the picture below.

*Alternative Answer*

We can see that the graph through the vertex and sure by using the formula case 1

Substitute (a) to the origin formula then we get

so the equation of the graph is

**Example 2**

Identify the graph function of quadratic equation of the picture below.

**Alternative answer**

We can see that the graph across x axis and through any point and sure by using the formula case 2

Substitute (a) to the origin formula then we get

##### Example 3

Identify the graph function of quadratic equation of the picture below.

**Alternative answer**

We can see that the graph through the vertex and any point x axis and sure by using the formula case 1

Substitute (a) to the origin formula then we get
