The graph represents a functional relationship.

which value is an input of the function?
–14
–2
0
4

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

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
