Let f(x) = -3x - 4 and g(x) = 2x - 6. Find f(x - 1).

Solution:

A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B.

A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math. 

Given functions:

f(x) = -3x - 4 and g(x) = 2x - 6

f(x) = -3x - 4

f(x - 1) = -3(x - 1) - 4

f(x - 1) = -3x + 3 - 4

f(x - 1) = -3x - 1

Let f(x) = -3x - 4 and g(x) = 2x - 6. Find f(x - 1)

Summary:

If f(x) = -3x - 4 and g(x) = 2x - 6 then f(x - 1) = -3x - 1
