The graph is not a function because there are two different y-values for a single x-value. Option (d) is correct.
Further explanation:
Given:
The options are as follows,
(a). It is not a function because the points are not connected to each other.
(b). It is not a function because the points are not related by a single equation.
(c). It is not a function because there are two different x-values for a single y-value.
(d). It is not a function because there are two different y-values for a single x-value
Explanation:
The output values of the function are known as range and the input values on which function is defined is known as the domain of the function.
The one-to-one function is a function in which every value of the range has exactly one pre-image in the domain.
One-to-one function always passes the vertical line test and the horizontal line test.
The given graph doesn’t pass the vertical line test.
