Table of Contents: Step 1: Finding the Vertex Step 2: Finding two points to left of axis of symmetry Step 3: Reflecting two points to get points right of axis of symmetry Step 4: Plotting the Points with table Step 5: Graphing the Parabola In order to graph , we can follow the steps: Step 1 Find the vertex the vertex is the either the highest or lowest point on the graph. Also, the vertex is at the axis of symmetry of the parabola ie it divides it in two. Step 2 Once you have the vertex, find two points on the left side of the axis of symmetry the line that vertically runs through the vertex. Step 3 Reflect those two points over the axis of symmetry to get two more points on the right side of the axis of symmetry. Step 4 Plot all of the points found including the vertex. Step 5 Draw a curve through all of the points to graph the parabola. Let's go through these steps in detail Jump to Top of Page Step 1 Finding the vertex: In order to find the vertex, we first need to find the x-coordinate of the vertex.

So the y-coordinate of the vertex is. Get Started. Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. How did we do? Our parabola opens up and accordingly has a lowest point AKA absolute minimum. The salary of A, B, C are in the ratio of 5 : 3 : 2. More Algebra Questions Q1. So the second point to the left of the axis of symmetry is 0,-1 Jump to Top of Page Step 3 Reflecting the two points over the axis of symmetry: Now remember, the parabola is symmetrical about the axis of symmetry which is This means the y-value for which is one unit from the axis of symmetry is equal to the y-value of which is also one unit from the axis of symmetry. So the first point to the left of the axis of symmetry is -1,2 Let's find the y value when Start with the given equation. For this reason we want to be able to find the coordinates of the vertex. Baby sitter charges Rs. He had lived one-third of his life as a boy, one- fifth of his life as a youth, one-fourth of his life as a man and the remaining 39 years as an old man. Also, the vertex is at the axis of symmetry of the parabola ie it divides it in two. The profit earned when an article is sold for Rs.
