Question

PLEASE CHECK ANSWER!! Which relationship shows a quadratic variation?

Answer 1

Answer:

Option D) shows quadratic variation.    

Step-by-step explanation:

We are given the following information in the question:

• Variation refers to a relationship between two variables.
• There are a number of different types of variation, such as direct variation or inverse variation.
• Quadratic variation to describe a  way in which two variables relate to one another.
• We could write quadratic variation as:

$y = kx^2$, where k is a constant.

Option D) is an example of quadratic variation and can be explained as:

For k = 3

$y(x) = 3x^2\\\\x = 1\\y(1) = 3(1)^2 = 3\\\\x = 2\\y(2) = 3(2)^2 = 12\\\\x = 3\\y(3) = 3(3)^2 = 27\\\\x = 4\\y(4) = 3(4)^2 = 48$

Hence, Option D) shows a relation of quadratic variation.
