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

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.... 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.

17/05/2011 · while you're working with a parabola given by technique of a quadratic formulation y = ax^2 + bx + c, then no. each such parabola would have a y-intercept, on account which you will in basic terms plug in x=0. regardless of if, you are able to rotate the parabola.... My teacher gave me this problem where I did a long jump and recorded the distance I went. He then asked us the height. My distance was 80 inches so the x-intercepts are $0,0$ and $80,0$. My questio...

**How to find formula of a parabola given y-intercept and a**

Its y-intercept can be written as the point (0,3). Example 2: Find the x and y-intercepts of the line y = –2 x + 4 . To find the x-intercepts algebraically, we let y = 0 in the equation and then solve for values of x . how to show suggested friends on snapchat 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 .

**X intercepts of a parabola" Keyword Found Websites Listing**

At these points of intersection the x-coordinate for the line equals the x-coordinate for the parabola, and the y-coordinate for the line equals the y-coordinate for the parabola. Since at the points of intersection the y-coordinates are equal, (we'll get to the x-coordinates in a moment), let's set the y-coordinate from line equal to the y-coordinate from parabola. how to use walgreens thermometer Related Questions.

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

11/11/2006 · 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.

- 21/03/2010 · in a quadratic function, the x-value of the vertex is the average of the x-intercepts of the function. the x-intercepts of the function are 2 and -2. thus, the average of 2 and -2 is 0. this means that the x-value of the vertex is 0. to get the y-value, just substitute the x-value into the equation:
- Its y-intercept can be written as the point (0,3). Example 2: Find the x and y-intercepts of the line y = –2 x + 4 . To find the x-intercepts algebraically, we let y = 0 in the equation and then solve for values of x .
