Answer:
the ordered pairs are (-1,3/4), (0,3), (1,12), and (2,48)
an exponential function looks like this:
y=ab^x
substitute the x and y values
3/4=ab^(-1)
3/4=a/b
3=ab^0
3=a*1
3=a, so b=4
y=ab^x
y=3(4^x) is the equation that you want
if x=-1, then y=3/4
if x=0, then y=3
if x=1, then y=12
if x=2, then y=3*4^2=3*16=48
