## How do you find the y-coordinate of a vertex?

Lesson Summary

- Get the equation in the form y = ax2 + bx + c.
- Calculate -b / 2a. This is the x-coordinate of the vertex.
- To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

**What is the vertex point formula?**

The vertex of a parabola is the point where the parabola crosses its axis of symmetry. In this equation, the vertex of the parabola is the point (h,k) . You can see how this relates to the standard equation by multiplying it out: y=a(x−h)(x−h)+ky=ax2−2ahx+ah2+k .

**How do you find the coordinates of the vertex of a parabola?**

To find the vertex of a parabola, you first need to find x (or y, if your parabola is sideways) through the formula for the axis of symmetry. Then, you’ll use that value to solve for y (or x if your parabola opens to the side) by using the quadratic equation. Those two coordinates are your parabola’s vertex.

### What is the vertex in Y?

(0, 0)

In the graph of y = x2, the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward.

**What is the y-coordinate of a root?**

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

**How do you find the Y coordinate?**

The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value “5” is the Y Coordinate.

## What is the Y coordinate?

Definition of y-coordinate : a coordinate whose value is determined by measuring parallel to a y-axis specifically : ordinate.

**What’s the y-intercept formula?**

The y-intercept formula says that the y-intercept of a function y = f(x) is obtained by substituting x = 0 in it. Using this, the y-intercept of a graph is the point on the graph whose x-coordinate is 0. i.e., just look for the point where the graph intersects the y-axis and it is the y-intercept.

**How do you find the coordinates on a graph?**

To identify the x-coordinate of a point on a graph, read the number on the x-axis directly above or below the point. To identify the y-coordinate of a point, read the number on the y-axis directly to the left or right of the point. Remember, to write the ordered pair using the correct order (x,y) .

### How do you find the X and Y coordinates of a vertex?

This is the x- coordinate of the vertex. To find the y- coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y- coordinate of the vertex. Click to see full answer.

**How to find the vertex coordinates of a parabola?**

The vertex formula helps to find the vertex coordinates of a parabola. The standard form of a parabola is y = ax 2 + bx + c. The vertex form of the parabola y = a (x – h) 2 + k. There are two ways in which we can determine the vertex (h, k). They are: (h,k), where h = -b / 2a and evaluate y at h to find k.
