How do you graph f(x) = 7 ?

Given equation is $f \left(x\right) = 7$.
Now functions of $x$ map their corresponding answer as a point with respect to the $y$ axis, which means $y = f \left(x\right) \setminus \implies y = 7$
The above equation says that the height of the point above the x-axis is $7$ units and stays that much regardless of what value of $x$ we choose.
