4 Warm-up #3: Graph an ellipse. Here are several ellipses from another class. Use the sketch tool to highlight two ellipses that could have the following equation: $$x − 5 2 4 + y + 5 2 1 6 = 1 Explain how you knew which ellipses to choose. 2. Kazrashura says: Nov 05, · Conic Sections: Parabolas, Part 3 (Focus and Directrix). Just another example of finding the focus and directrix for a parabola (a slightly more involved example). 3. Kazilmaran says: Parabola definition is - a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line: the intersection of a right circular cone with a plane parallel to an element of the cone. 4. Mooguzilkree says: From the graphing calculator, we see that the vertex is $$\left({,} \right)$$. The maximum rabbit population was roughly rabbits (we can’t have half of a rabbit!) when it was months after they began observing the rabbit population. This answers (a) and (b) above. 5. Zulkikree says: Mar 02, · For a parabola, the equation is y 2 = -4ax. Now, to represent the co-ordinates of a point on the parabola, the easiest form will be = at 2 and y = 2at as for any value of “t”, the coordinates (at 2, 2at) will always satisfy the parabola equation i.e. y 2 = 4ax. So, Any point on the parabola. y 2 = 4ax (at 2, 2at) where ‘t’ is a parameter. 6. Tomi says: Jun 02, · In this section we will be graphing parabolas. We introduce the vertex and axis of symmetry for a parabola and give a process for graphing parabolas. We also illustrate how to use completing the square to put the parabola into the form f(x)=a(x-h)^2+k. 7. Zulugore says: Off axis parabola – Part 3 (Multi-beam delivery system) Off axis parabola – Part 4 (Tip about front face) Off axis parabola – Part 4 (Tip about front face) Practice time: multi-configs and atlabolturendiamanfiesiorydisfpret.co Dispersive prism. 8. Tygoshura says: And that line, I didn't draw it as neat as I should, that should go directly through the vertex, so to describe that line you'd say that line is x is equal to Similarly the axis of symmetry for this pink parabola, it should go through the line x equals negative one, so let me do that. That's the axis of symmetry. 9. Netaxe says: The line$$ x = -3 $$is this parabola's axis of symmetry. Problem 4. What is the axis of symmetry of the parabola$$ y = (x - 3)^2 + 4 $$Axis of Symmetry. Since this equation is in vertex form, use the formula$$ x = h$$The axis of symmetry is the line$$ x = 3 Problem 5.
