which function represents the graph of y=3(1/2)^x ?

a) a

b) b

c) c

d) d

I belive this would be B.
Attached is what goes with y=3(1/2)^x
Hope this helps!

Exponential equation: y=a*b^x
first, eliminate a and d, because a=3, a positive number, y will not be negative.
next, look at b, b=1/2, a number smaller than 1, so the bigger x is, the smaller (1/2)^x will be. It is a decay. 
b is the correct answer 

It’s d for sure i just did also that’s why
