Question

If f(x) = 7x − 1, what does f(12) represent?

A. The value of x when (7x − 1) = 12
B. The value of (7x − 1) when x = 12
C. The value of 12 f(x) when x = 12
D. The value of f(x) when (7x − 1) = 12

Answer 1

hello :
f(12) represent : B. The value of (7x − 1) when x = 12

Answer 2

f(12) represents the value of (7x − 1) when x = 12

Explanation:

f(x)= 7x -1

We need to find what does f(12) represents

f(x) = 7x -1

f(12) represents f(x) when x= 12

f(12) is f(x) so we can say x=12

f(12) represents that we need to find the value of 7x -1 when x= 12

That is we plug in 12 for x and find the value of f(12)

f(12) represents the value of (7x − 1) when x = 12
