Answer 1

Last answer choice: 4

Explanation:

The set of inputs to the graphed function is he set of all x values for which the function has a defined value

Looking at the answer choices we see that the graph does not go the negative x region nor does it have a value for 0

So x = 4 is an input, and the resultant output y from the graph = 0
