Question

How do you graph `f(x) = 7`?

Answer 1

A line parallel to the x-axis and at a distance of 7 units above the x-axis.

Explanation:

Given equation is `f(x)=7`.
Now functions of `x` map their corresponding answer as a point with respect to the `y` axis, which means `y=f(x) \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.
