Answer:
f(x)=x-2 translation
Step-by-step explanation:
Since the line is shifted down 3 units, you would subtract 3 from the y-intercept. This type of transformation is a translation.
Shifting up and down affects the y-int. Shifting left and right would affect an exponent (not present in this question)
I would appreciate a brainliest but it's ok either way :) I hope this helped
