The given function f(x) = 4x - 12, gives the value of f(2) = -4.
Hence, option D is the right choice.
What is a function?
A function is a relation between a dependent variable f(x) and an independent variable x, where for every value of x in its domain, there is one and only one value of f(x).
How do we solve the given question?
In the question, we are given a function f(x) = 4x - 12.
We are asked to find the value of f(2).
To find the value of f(2), we substitute x = 2 in f(x) = 4x - 12.
∴ f(2) = 4(2) - 12 = 8 - 12 = -4.
∴ The given function f(x) = 4x - 12, gives the value of f(2) = -4.
Hence, option D is the right choice.
