Question 35459
the numbers decrease as the x-values go lower....but the y-values never
are equal to or lower than 0 .... so it must be an exponential function!
use y=(a)(b^x)
y=(a)(b^x)
1=a(b^0)
a=1
so: y=b^x
4=b^1
b=4
so your final equation is:
y=4^x
------------------------------------
the domain and range are the same as in the graph as they are in your list
domain: all real number
range: y>0
sorry, I do not know how to plot an exponential growth equation to show you
