ghow to choose x values for graphing quadratic polynomial

Answer 1

Here is ur answer!!

First, we should know about the properties of the quadratic equation.

It is better for us to choose x pairing side by side, left and right from symetrical axis of the equation.

So, our graph will be including its maximum or minimum point.

We can use formula x=-b/2a to search value symetrical axis.
