Answer:
f(x) = x - 2
Step-by-step explanation:
If you notice, the f(x) or y value is 2 less than the x value for every x value listed. This means that x - 2 = y. Just by rearranging this equation, you are given an equation in the linear form y = mx + b:
y = x - 2
Since the y coordinate is being represented by f(x) in the equation, as it is a function, the answer would be:
f(x) = x - 2
