The y variable stands for the y value in an equation like x+y=1
$2.00=100%-25%=75%
50%=$1.00
so that means 75% =$ 1.50
Answer:
Domain: X is an element of real number
It is a function
Step-by-step explanation:
x is an element of all real numbers
y=5x has a one to one relation. It is a function
Ok to figure out if one is an inverse function, you plug in y for x and substitute f(x) with x and solve for y.
We only have to do this for 1 of the functions so we will take f(x)
x = 5y +1/y
I’m not sure you can solve for y here therefore g(x) is not an inverse function of f(x)
I think the answer would be 41.28
