Which function in vertex form is equivalent to f(x) = x2 + 6x + 3?

Step-by-step explanation:

we have

we know that

The equation of a vertical parabola into vertex form is equal to

where

(h,k) ------> is the vertex of the parabola

Convert the function into vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side

Rewrite as perfect squares
