y-1 = f(x)
Step-by-step explanation:
Here, we want to select the equation for the red graph
As we can see, the difference between the two is a vertical translation by 1 unit
What this mean is that the equation of the rear graph is an upward vertical translation from the black
thus, we have this as;
y = f(x) + 1
which is same as
y-1 = f(x)
