Answer:
1. If k > 0 then the parent function will shift up by k units
2. If k < 0 then the parent function will shift down by k units
Step-by-step explanation:
The parent function is y = f(x) and we have added a constant k to this function to create the function y = f(x) +k.
If we add some constant k in the function then there would be a translation in vertical direction. The function will either shift up or down depending on the constant k.
For the function y = f(x) +k, we have below transformations in the parent function.
1. If k > 0 then the parent function will shift up by k units
2. If k < 0 then the parent function will shift down by k units.
