Answer: Upper right corner
The base 0.2 is between 0 and 1, which means that we have a decaying exponential function. The curve will go downhill as you read from left to right. If the base were larger than 1, then we'd have an exponential growth function.
If you plugged in x = 0, then you'd get
y = 0.2^x + 3
y = 0.2^0 + 3
y = 1 + 3
y = 4
So the point (0,4) is on this graph. Only the upper right corner fits the description that it both decays and it has (0,4) on the curve.
