the graph represents a functional relationship. on a coordinate plane, a straight line with a negative slope begins at point (1, 3), crosses the x-axis at (4, 0), and exits the plane at (18, negative 14). 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:

Let

x -----> the independent variable or input value

y ----> the dependent variable or output value

we know that

Looking at the graph

The domain (input values) of the linear function is equal to the interval

[1,∞)

All real numbers greater than or equal to 1

The range (output values) of the linear function 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
