Math Quadratic functions Reflect the standard parabola

Reflect the standard parabola

The standard parabola can also be reflected by the parameter $a$. The general formula is:

$y=ax^2$
!

Remember

  • If $a$ > 0, the parabola is open at the top.
  • If $a$ < 0, the parabola is opened down.

Example

$\color{blue}{f(x)=x^2}$
$\color{green}{g(x)=-x^2}$
