Answer:

D. 4

Explanation:

We have been given graph of a function. We are asked to choose the value, which is input of the given function.

We know that input of a function is value of the independent variable. Upon looking at our given graph, we can see that x is independent variable.

All the values in domain of our a function will be input values.

We can see that domain of our given function is
$[1,\infty)$ .

Our function is defined for x values that are greater than or equal to 1, so first three options are not correct choice.

Since our function is defined at
x=4 , therefore, 4 is an input of the given function.
