Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). A parabola is given by the equation y = x2 + 4x + 4. The vertex of the parabola is _. The focus of the parabola is _. The directrix of the parabola isgiven by the equation y = _. Note: Separate coordinates inside parentheses with a comma.

Hello, What you have is a quadratic equation. First let us obtain the vertex, to find the x-vertex it can be done by using: \[\dfrac{-b}{2a}\] After you get the x-vertex, you need the y-vertex to create the coordinate pair, you can obtain the y-vertex by subbing the new found x-vertex into your original equation. Tell me what you get so I can check it you understood that much so far, if not I can break it down into pieces.
