Question

What is the inverse of this function

Answer 1

g(x) = (25 - x)/5 First lets call g(x) by its other name - y

y = (25 - x)/5 Now switch the x and y

x = (25 - y)/5 Solve for y which is now the inverse - call this
`g^(-1)(x)`

5x = 25 - y
y = 25 - 5x this is the inverse so
`g^(-1)(x)` = 25 - 5x
