If f(12)=4(12)-20, what function gives f(x)

Step-by-step explanation:

We have been given that

In order to find the function f(x), we can use the concept of substitution.

Let us suppose we need to find the value of the function f(x) at x = 12. Then, we can substitute x = 12 in the function f(x).

Here,

It means that x is replaced with 12.

So f(x) should be
