Step-by-step explanation:
Answer:
f^-1 (x) = 1/2x -5/2
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y = 2x+5
Exchange x and y
x = 2y+5
Solve for y
Subtract 5 from each
x-5 = 2y+5-5
x-5 = 2y
Divide by 2
(x-5)/2 = 2y/2
1/2x - 5/2 = y
f^-1 (x) = 1/2x -5/2
