Answer:
The value of 4 is an input of the function
Step-by-step explanation:
Define the variables
Let
x ----> the independent variable or input value
y ----> the dependent variable or output value
Looking at the graph
The domain of the graph (all possible values of x) is equal to the interval
[1,∞)

All real numbers greater than or equal to 1
The range of the function (all possible values of y) is equal to the interval
(-∞,3]

All real numbers less than or equal to 3
therefore
The value of 4 is an input of the function
