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.
