Question

Determine whether the equation represents direct, inverse, joint, or combined variation. y=7x^3

Answer 1

Explanation:

The equation y = 7x^3 represents direct variation.

In direct variation, when one variable increases, the other variable also increases proportionally. In this case, as x increases, y increases at a rate proportional to the cube of x (since x is raised to the power of 3). The constant of variation in this case is 7.
