  Examples of Inverse Variation Example 1: Tell whether y varies inversely with x in the table below. If yes, write an equation to represent for the inverse variation. Solution: In order for the table to have an inverse variation characteristic, the product for all pairs of x and y in the data set must be the same.

  This particular inverse relationship can be called an inverse variation, because the speed and time values have a constant product, a distance of 120 miles. This constant product makes it possible to create an equation for the inverse variation. All inverse-variation equations are of the form y = k x, where k is the constant of variation. Have ...

  The word “inverse” suggests that as one variable increases in value, the other variable decreases in value. However, the meaning of inverse variation is more specific than this.The relationship between two non-zero variables, x and y, is an inverse variation if y = or xy =k where k is a constant that is not 0.The value of k is determined ...

  DIRECT AND INVERSE VARIATION . This unit is about direct and inverse relationships. Direct variation is a linear function defined by an equation of the form y = kx when x is not equal to zero. Inverse variation is a nonlinear function define d by an equation of the form xy = k when x is not equal to zero and k is a nonzero real number constant.

  This is inverse variation: x gets bigger, y gets smaller. Basic practice In the following, do x and y vary directly or inversely? To figure this out, get x and y on opposite sides of the equation. Check if they are both in the top (direct variance) or one on top and the other on the bottom (inverse variance): 1) 3 4 xy = 2) 3 4 x y
