For the data in the table, tell whether y varies directly with x. If it does, write an equation for the direct variation.
allochka39001 [22]

It is direct variation if x/y is a constant.

x/y = 2 / -6.6 = -1/3.3

y/x = -9.9/3 = -3.3

y/x = -6.6/ 2 = -3.3

y/x = -13.2/ 3 = -3.3

y/x = -16.2/ 3 = -3.24

So its not exactly direct variation as the last values is slightly different from the first 3.

What is the inverse of f(x)=(3x)2 for x≥0
vitfil [10]

The inverse of the function f(x) = (3x)^2 is f-1(x) = 1/3√x

<h3>How to determine the inverse of the function?</h3>

The function is given as:

f(x) = (3x)^2

Remove the bracket in the above equation

So, we have:

f(x) = 9x^2

Express f(x) as y

So, we have

y = 9x^2

Swap the positions of x and y

So, we have

x = 9y^2

Make y the subject of the formula

y^2 = x/9

Take the square root of both sides

y = 1/3√x

Express as an inverse function

f-1(x) = 1/3√x

Hence, the inverse of the function f(x) = (3x)^2 is f-1(x) = 1/3√x
