Answer:
f^-1(x) = (x/8)^(1/5) is a function
Step-by-step explanation:
The inverse of a function is the function reflected across the line y=x. This results in the coordinate points (x,y) of the function becoming (y,x) for the inverse function. Algebraically to find the inverse, switch the x and y locations and solve for y.
y = 8x^5
x = 8y^5
x/8 = y^5
(5)√(x/8) = y
This is a fifth root of (x/7) also written in exponents as y = (x/8)^(1/5).
This is a function. While it appears not to be a function because the middle portion over the origin appears vertical, it is a function because the middle portion over the origin is changing and graphing software shows it has no input with more than one output. Without graphing software you would rule it is not a function.

You would take the beginning number and subtract the second number then you would take the number you got and divide it by the first number.
1420-1022=y then y/1420
There is a 20:12 chance that there is a small size, now that would be a answer but I suggest simplifying the answer so divide them by 4 since that's the greatest common factor. So, 20/4=5 & 12/4=3 so there is a 4:3 chance that you get a small sized sweater.
