Answer:
f-1 (x) = 2x + 2
Step-by-step explanation:
f(x) = x/2 -1
y = x/2 -1
interchanging the position of x and y
x= (y-2)/2
2x =y - 2
y = 2x + 2
f^-1 (x) = 2x + 2
Asociative property of multiplication
It would be 14y.... if you combine like terms you would get the following:
7(2y)
7•2
14y
3x-5y=25 i hope this helps
