Transform the given quadratic function into vertex form f(x) = quadratic function into vertex form f(x) = quadratic function into vertex form by completing the square. by completing the square.

Step-by-step explanation:

The Vertex form of a quadratic function is , where is the vertex of the parabola, and the sign of the coefficient indicates if the parabola opens down or opens up.

The Standard form of a quadratic function is , where the sign of the coefficient indicates if the parabola opens down or opens up.

To transform a quadratic function from Standard form  to Vertex form, you need to complete the square.

Given the quadratic function :

Indentify a:

Factor out -4:

Take the coefficient b and add and subtract to keep the balance:

Now rewrite the expression in the form , this is:

answer: c i think

step-by-step explanation:

the answer is c

hope this !
