Let us begin by defining the graph of a function
The graph of a function f is the set of all points in the plane of the form (x, f(x))
Given:
f(x) = 6.
We are required to find the x at f(x) =6
From the graph, we can see that there are two points that has the value of f(x) to be equal to 6. Hence, the x-values of these points are:
