**Finding the x and y Intercepts ChiliMath**

The vertex form tells you the vertex of the parabola, which way it opens, and whether it is a wide or narrow parabola. Using the standard equation of y=ax^2+bx+c, find the x value of the vertex point by plugging the a and b coefficients into the formula x= -b/2a....

Example 3: Find the x and y-intercepts of the quadratic equation y = x 2 − 2 x − 3. The graph of this quadratic equation is a parabola. We expect it to have a “U” …... Compare y = -x 2 to y = x 2. Because the coefficient of - x 2 is -1, then a = -1. When a is negative 1 or negative anything, the parabola will flip 180 degrees.

However, if you have messy x-intercepts (as in the example above) or if the quadratic doesn't actually cross the x-axis (as you'll see on the next page), then you'll need to use the formula to find the vertex.... Here I've drawn the most classic parabola, y is equal to x squared. And what I want to do is think about what happens-- or how can I go about shifting this parabola.

20/02/2013 · y = a(x - h)² + k This is the equation of a vertical parabola with vertex (h, k). The axis of symmetry is the vertical line x = h. A change in h moves the vertex and axis of …... The simplest equation for a parabola is y = x 2 . Turned on its side it becomes y 2 = x (or y = √x for just the top half) A little more generally: y 2 = 4ax. where a is the distance from the origin to the focus (and also from the origin to directrix) Example: Find the focus for the equation y 2 =5x. Converting y 2 = 5x to y 2 = 4ax form, we get y 2 = 4 (5/4) x, so a = 5/4, and the focus of y

### Example 3: Find the x and y-intercepts of the quadratic equation y = x 2 − 2 x − 3. The graph of this quadratic equation is a parabola. We expect it to have a “U” …

- Determine if there are any x-intercepts, either by comparing the shape of the parabola and the vertex, or by checking the discriminant of the expanded function. Find the x -intercepts, if they exist.
- 3/11/2015 · We have x^2 + 8x + 3 = y We want to change this to the vertex form. Step 1 is to group our x values together and complete the square.so we can …
- The graph of y=(x-k)²+h is the resulting of shifting (or translating) the graph of y=x², k units to the right and h units up. For example, y=(x-3)²-4 is the result of shifting y=x² 3 units to the right and -4 units up, which is the same as 4 units down.
- The vertex form of a parabola's equation is generally expressed as: y = a(x-h) 2 +k (h,k) is the vertex as you can see in the picture below If a is positive then the parabola opens upwards like a regular "U".
