This equation has no solution
We can solve this question in the following way. Looking at the graph, we see that F(x) is shifted from one unit to the right, and it is represented by | x - 1|. Then, we can multiply this result by 4 to have the final graph, since the graph is not inverted.
Therefore, the answer to this question is F(x) = 4 * | x - 1 |.
