Question

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

Answer 1

The value of 4 is an input of the function

Explanation:

we know that

In a linear equation, the variable x represent the independent variable or input value and the variable y represent the dependent variable or output value

In this problem we have that the given line passes through the points (1,3), (4,0) and (18,-14)

so

The input values are (1,4,18)

The output values are (3,0,-14)

therefore

The value of 4 is an input of the function
