Question

find the inverse of the given one-to-one function below. (show your complete solution)​

Answer 1

I don't know the first one but will try to answer 2 and 3

2. g(x) =5x-3

let g(x) = y, we need find g-¹(y) = x

y=5x-3

5x=y+3

x = (y+3)/5

g-¹(y) = (y+3)/5

3. f(x) = x-6/2 =y

2y= x-6

x=2y+6

f-¹(y) = 2y+6
