Question

Inverse of the letter a​

Answer 1

We have the function f(x) = 2x + 3

the processes which take place in this function are

we take x [x]

we multiply it by 2 [2x]

we add 3 to it [2x + 3]

To get the inverse of this function, we will do exactly the opposite of it

we will take the output of the initial function [y]

we will subtract 3 from it [y-3]

we will divide it by 2 [(y-3)/2]

We get the function:

`f^(-1)`(y) = (y-3) / 2

Inverse functions are used to get the initial value used in the function bu using the output of the function

`f^(-1)`(0) = (0-3)/2

`f^(-1)`(0) = -3/2

Therefore, the input of the function is -3/2 when the output is 0
