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**. Substitute the found value of x into the original equation to find the value of y. The values of x and y are the coordinates of the vertex.

## Hereof, how do you convert an equation from vertex form to intercept form?

**y=mx+b**. We want to isolate the y, so our first step is to multiply both sides by 9. Then cancel out the 9’s on the right side. Then subtract 36 from both sides.

## Beside this, how do you go from vertex form to standard form?

**Vertex form to standard form converter**

- Write the parabola equation in the vertex form: y = a*(x-h)² + k ;
- Expand the expression in the bracket: y = a*(x² – 2*h*x + h²) + k ;
- Multiply the terms in the parenthesis by a : y = a*x² – 2*a*h*x + a*h² + k ;

## Is intercept form and vertex form the same?

Vertex form is used to find the vertex of the function to graph it. Intercept form is used for **completing** the square or finding the intercepts or solutions of the graph.

## What is P and Q in intercept form?

The intercept form of a quadratic function is **y=a(x-p)(x-q)**, where p and q are the x-intercepts of the function.

## What is the vertex in vertex form?

The vertex form of a quadratic is given by **y = a(x – h) ^{2} + k**, where (h, k) is the vertex. The “a” in the vertex form is the same “a” as in y = ax

^{2}+ bx + c (that is, both a’s have exactly the same value). The sign on “a” tells you whether the quadratic opens up or opens down.

## What is vertex form?

The vertex form of an equation is **an alternate way of writing out the equation of a parabola**. … From this form, it’s easy enough to find the roots of the equation (where the parabola hits the x -axis) by setting the equation equal to zero (or using the quadratic formula).
