The equation is a function
Explanation:
Given that the graph contains the coordinates ,
,
and
We need to determine whether the equation is a function.
To determine the equation is a function, let us substitute the coordinates in the equation and check whether it satisfies the equation.
Let us substitute the coordinate in the equation
Thus, we have,
Thus, the coordinate satisfies the equation
Substituting the coordinate in the equation, we have,
Thus, the coordinate satisfies the equation
Substituting the coordinate in the equation
Thus, the coordinate satisfies the equation
Substituting the coordinate in the equation, we get,
Thus, the coordinate satisfies the equation
Hence, the coordinates ,
,
and
satisfies the equation
Thus, the equation is a function.
