Respuesta :
Take the f(x) and replace with y to get
y = .5x + 10.
Then flip the y and x to find the inverse.
x = .5y + 10
Now solve for the new y..
x - 10 = .5y
2x - 20 = y.
The missing value is 20.
y = .5x + 10.
Then flip the y and x to find the inverse.
x = .5y + 10
Now solve for the new y..
x - 10 = .5y
2x - 20 = y.
The missing value is 20.
