Hello. I am really terrible with the applications, and I would be very grateful if someone could help me to answer this question.
I have started with writing the equation y=0.9375^(x)
I checked if it passes through the point (0,1) and it does pass. Then I checked if it passes through the point (2, 0.0625) and it does not pass, so I tried to rewrite the equation as y=0.9375^(x/2) and y=0.9375^(2x)
....and none of the equations worked out
