Verex form of a quadratic function

Consider the following function f(x)=-4x^2+4x+3. Change f(x) into vertex form. 

1 Answer

We try to write this fuunction $f(x)=-4x^2+4x+3$ in the vertex form $y = a(x - h)^2+ k$. 

We will do this by factoring the coefficient of $x^2$ first and then completing the square: 
which is in the vertex form.

  • There was a mistake in my solution. I have revised it.

      also, it's vertex , not vortex. ;-)

    • Thank you, M F H. I fixed the typo.
