Direct Variation A direct variation is a special type of linear relationship. It can be written in the form y kx where k is a nonzero constant called the constant of variation. You can identify direct variations from equations or from ordered pairs. Tell whether 2x 4y 0 is a direct variation. If so, identify the constant of variation. variation.

Inverse functions mc-TY-inverse-2009-1 An inverse function is a second function which undoes the work of the first one. In this unit we describe two methods for finding inverse functions, and we also explain that the domain of a function may need to be restricted before an inverse function can exist.

Inverse and joint variation 9.1.1. One of the first things that scientists do with data is to graph it in various ways to see if a pattern emerges. If two variables are selected that lead to a smooth curve, the variables can be shown to lead to ‘correlated’ behavior that can either represent a direct, or inverse, variation. The specific

JOINT VARIATION There are situations when more than one variable is involved in a direct variation problem. In these cases the problem is called joint variation. The equation remains the same except that additional variables are included in the product. For example if A varies jointly with the values of b and h the equation will be A kbh.

Combined Variation, the proportion is both direct and inverse whereas in Joint Variation, the proportion is direct. Also, it can be said that Joint variation is associated with the product of the several variables while Combined Variation is associated with both the product and quotient of the several variables. Let’s study both cases.

Write a direct variation equation that relates x and y. Then solve. If y 6 when x 10, find x when y 18. 62/87,21 So, the direct variation equation is Substitute 18 for y and find x. So, x 30 when y 18. If y 22 when x 8, find y when x 16. 62/87,21 So, the direct variation equation is . Substitute 16 for x and find y.

200 Chapter 5 Ratios and Proportions 5.6 Lesson Direct Variation Words Two quantities x and y show direct variation when y kx, where k is a number and k 0. The number k is called the constant of proportionality. Graph The graph of y kx is a line with a slope of k that passes through the origin. So, two quantities that show direct variation are in a proportional relationship.
