Answer:

y = -(4)^x + 3

Explanation:

at x=0, y=2 so that rules out the two middle choices

at x=1, y=-1 so that rules out the last choice

ans is the first y = -(4)^x + 3

y=a^x\\\\if\ a>1,\ then\ the\ graph\ is\ increase\ and\ has\ positives\ values\ of\ y\\\\if\ a\in(0,\ 1),\ then\ the\ graph\ is\ decrease\ and\ has\ positives\ values\ of\ y\\\\y=-a^x\\\\if\ a\in(0,\ 1),\ then\ the\ graph\ is\ increase\ and\ has\ negatives\ values\ of\ y\\\\if\ a>1,\ then\ the\ graph\ is\ decrease\ and\ has\ negatives\ values\ of\ y


f(x)+n\to translate\ the\ graph\ n\ units\ up\\\\f(x)-n\to translate\ the\ graph\ n\ units\ down\\\\


\text{We have the decrease graph with negatives values of y}.\\\\\text{Therefore your answer is}:\ \boxed{y=-4^x+3}
