Well, we can evaluate the axis of symmetry, focus, directrix, vertex, x intercept, y intercept by using the parabola formula in the form of \( x = y^2 + bx + c \). By taking the time to explain the problem and break it down into smaller pieces, anyone can learn to solve math problems. Remember the pythagorean theorem. This parabola is of the form {eq}{(y-k)}^2=4p(x-h) {/eq} so it opens horizontally. So if you square both sides, Example: If the by two times, b minus k. So, let's divide everything, two times, b minus k, so, two times, b minus k.
