Answer:
graph it
Step-by-step explanation:
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.
Answer:
7/7
Step-by-step explanation:
The fraction 7/7 is considered to be improper by most mathematicians. The definition of a proper fraction is that the numerator is less than the
Its either a or c im not entirely sure which one but I do know it has to be in parentheses.
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
