Let f(x) = 12 over the quantity of 4x + 2. find f(-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, f(x) = 12 over the quantity of 4x + 2.

We have to find f(-1).

f(x) = 12/(4x + 2) —---------------- (1)

To find f(-1), put x = -1 in (1)

f(-1) = 12/(4(-1) + 2)

= 12/(-4 + 2)

= 12/(-2)

= -6

Therefore, f(-1) is -6.

Let f(x) = 12 over the quantity of 4x + 2. find f(-1).

Summary:

Let f(x) = 12 over the quantity of 4x + 2. f(-1) = -6.
