Which function matches the table? A) ƒ (x) = x + 1 B) ƒ (x) = 1 C) ƒ (x) = x2 D) ƒ (x) = x - 1

f (x) = x + 1

Step-by-step explanation:

Remember, f (x) is a term for y. It means function of x, or in other words, what does y equal when x equals ___? If it makes it easier, think about these questions, replacing f (x) with y.

The table shows that y is just x + 1. You could figure this out by looking at the difference between corresponding x and y values.

1 - 0 = 1

2 - 1 = 1

etc.

They all have a difference of 1.

Therefore, the final answer is f (x) = x + 1.
