# How do you identify the important parts of #f(x)= x^2 - 10x + 5# to graph it?

##### 1 Answer

The point at which curve turns is the most important part of a graph.

#### Explanation:

Let

The important part of the graph is where the curve turns.

Quadratic functions normally have only one turn.

Either, it will decrease,turn and then increase or it will increase, turn and then decrease.

Since coefficient of

The vertex gives you where the curve turns.

At

At

Now take a few points on either side of
