What information can you get from factored form?

The factored form of the equation tells us the roots, i.e. the -intercepts, and . The key information in drawing a parabola is the vertex, which we can read off from the vertex form equation as the point .

What does R and S mean in factored form?

In factored form, the zeros are r and s. The vertex of the parabola is halfway between the two zeros. To find the x coordinate of the vertex, add the two zeros together and divide by two. In both forms, a determines if the parabola opens upward or downward.

What is an example of factored form?

A fully factored form means the given number or polynomial is expressed as a product of the simplest possible form. For example, if we write 12y2−27=3(4y2−9) 12 y 2 − 27 = 3 ( 4 y 2 − 9 ) , then it is not considered as fully factored form as (4y2−9) ( 4 y 2 − 9 ) can be factored further.

What does intercept form tell you?

Intercept Form of a Parabola The intercept form is y = a(x – r)(x – s), where r and s are the x-intercepts on the graph. The intercept form will tell us if there are two x-intercepts, one x-intercept or no x-intercepts.

Why is it called intercept form?

One form of the equation of a straight line is called the slope-intercept form because it contains information about these two properties. The value of c is called the vertical intercept of the line. It is the value of y when x = 0. When drawing a line, c gives the position where the line cuts the vertical axis.

What is the first step in converting to slope intercept form?

Thus, to convert to point-slope form, first convert to slope-intercept form, then move the constant term b to the left side of the equation (or isolate x and then divide by the y coefficient). Example: Convert 3x = 4y + 8 to point-slope form.

What does standard form look like?

An equation in standard form looks like ax + by = c; in other words, the x and y terms are on the left side of the equation and the constant is on the right side. The constant and both of the coefficients must be integers. The coefficient of the x-term must be positive.
