We are given parent function:
We need to explain which graph would represent f(x) +1. function.
Please note: 1 is added to parent function f(x).
According to rule of transformations y= f(x)+K shifts K units up of parent function f(x).
For parent function f(x) =2^x, y-intercept is 1.
So, for f(x)+1 function y-intercept would be 2 because y-intercept 1 is being shifted 1 unit up, that is 2.
So, the shown graph would be correct graph for f(x)+1.

Step-by-step explanation:
Original Question:
- Nana has a water purifier that filters 1/3 of the contaminants each hour. She used it to purify water that had 1/2 kilogram of contaminants. Write a function that gives the remaining amount of contaminants in kilograms, C(t), t hours after Nana started purifying the water.
Explanation:
- Each hour, the water purifier filters 1/3 of the contaminants, meaning that the contaminant reduces by 2/3. If the contaminant was 1kg (for example), the mass would be 2/3 kg after 1 hour- after 2 hours, it'll be 4/9 kg, so we see a pattern. We need to multiply the contaminant by 2/3 every single hour.
