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

Solution:

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.
