Step 3:Find the focus and directrix of the parabola. Because this parabola opens horizontally, we use the formula(h+p,k)to find the focus. Focus:(5+3,2)=(8,2) We use the equationx=h−pto find the directrix. Directrix: x=5−3x=2 ...

If the coefficient is positive, it opens upward; if negative, the parabola opens downward. 5. Focus and Directrix In the context of conic sections, the focus is a fixed point through which all light rays parallel to the axis of symmetry will reflect off the parabola. The directrix is a ...

To find theuniquequadratic function for our blue parabola, we need to use 3 points on the curve. We can then form 3 equations in 3 unknowns and solve them to get the required result. On the original blue curve, we can see that it passes through the point(0, −3)on they-...
Rewrite the equation, leaving an empty space on the right side of the equation after the "x" term but before the end parenthesis. Divide the coefficient of the "x" term by 2. In y + 10 = 2(x^2 + 4x), divide 4 by 2 to get 2. Square this result. In the example, square 2,...
