The graph no. 3 is not the graph of a function of x
What is a Function ?
A function is a mathematical expression where there are two variables , one is dependent variable and the other is the independent variable.
Every function has a domain and a range.
After we've substituted the domain, the range of a function is the entire set of all potential outcome values of the dependent variable (typically y)
A function is generally denoted by f(x) where x is the input.
In the given graphs it has to be determined that which graph is not a function of x .
It can be clearly seen from the image and the options that the option C has the equation
y = c.
As the graph is not dependent upon the value of x .
Therefore the graph y = c , option C is not the graph of a function of x.
