Parabola (1) with two x-intercepts and a y-intercept . Parabola (2) with one x -intercept and a y-intercept . Parabola (3) with no x -intercepts but there is a y-intercept .... Question 203134: Without drawing the graph determine how many x- intercepts the parabola has and whether its vertex lies above or below or on the x axis Show your work y = x^2 - 5x + 6 Found 2 solutions by jsmallt9, jojo14344 :

**given the vertex of (-2 1) and the intercept of (05**

To specify one particular parabola, you need values of a, b, c. Life is made a little easier here, because one of the points you are given is the y-intercept: no matter what a and b are, the parabola will go through (0,c) (because when you put x=0 in, the a and b terms become zero but the c term doesn't).... Related Questions. Find the x-intercepts for the parabola: y = x^2 + 4x - 3; 2 educator answers Determine the quadratic function of a parabola with x-intercepts x = 7 andx = -2 and y-intercept...

**Parabolas in Standard Intercept and Vertex Form Video**

If the quadratic equation is in standard form y = ax^2+bx+c, then the simplest way to think about the equation where it crosses the y-axis is that the y-axis has the value of X equals zero.... Depending on how high the parabola is located on the y-axis, an equation may have zero, one or two x-intercepts but it will always have one y-intercept. Check to make sure your equation is a quadratic equation by writing it in the form y = ax squared + bx + c where a, b, and c â€¦

is the maximum or minimum value of the parabola (see picture below) is the turning point of the parabola; the axis of symmetry intersects the vertex (see picture below) How to find the vertex. Depends on whether the equation is in vertex or standard form . Finding Vertex from Standard Form. The x-coordinate of the vertex can be found by the formula $$ \frac{-b}{2a}$$, and to get the y value of... Use this data to set up a system of 3 equations and 3 unknowns (a, b, and c) that will allow you to find the equation of the parabola. b. Use matrix manipulation to solve for a, b, and c.

## How To Work Out The Y Intercept Of A Parabola

### 16/09/2014Â Â· You will notice that, towards the end of the video, I use the heading "y-Intercept (x=0)." When analysing quadratic equations, I like to start each of the four sections with a heading that

- To start out, the equation of a parabola is y = (x-a) 2 + b where a and b are constants. The point (a,b) is the vertex of the parabola. So in your case, if you take -2 and 1, the equation would now look like y â€¦
- 11/11/2006Â Â· Best Answer: Let's start from the beginning with a quadratic. Let y=f(x)=ax^2+bx+c, where a is not equal to zero. The y-intercept is the point where the parabola intersects the y-axis.
- y-intercept occurs when x=0 for the first parabola, this is point (0,0) for the second parabola,this is point (0,9) They differ by 9.
- To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form). In this case, we end up with the square root of a negative number, so there are no x-intercepts.
