The equation provided in the image is $g(x) = c \cdot f(a \cdot x - b) + d$. We are tasked with finding the values of $a$, $b$, $c$, and $d$ based on the graph provided.

Looking at the graph:

• The function has a horizontal step at $y = 2$, and it jumps to $y = 4$ at $x = 0$, and then remains constant at $y = 4$.

From this, we can deduce the following:

1. Shift along the x-axis (b): The step occurs at $x = 0$, so there doesn't seem to be any horizontal shift. Thus, $b = 0$.

2. **
