Final answer:
To formulate a function f(x), define a relationship between input and output values. The inverse function f⁻¹(x) is found by swapping input and output variables.
Step-by-step explanation:
Formulating a Function and Its Inverse
To formulate a function f(x), we need to define a relationship between the input values (x) and the corresponding output values (f(x)). For example, we can define f(x) = 2x, where the output value is twice the input value.
To find the inverse function f⁻¹(x), we swap the input and output variables. In this case, f⁻¹(x) = x/2, where the input value is divided by 2 to obtain the original input value of f(x).
