Question 1124191
----------
a. Suppose f is an exponential function and f(0)=8 and f(1)=18. Write a function formula for f. 
-what is f(x)= 
---------


{{{y=pb^x}}}


{{{system(pb^0=8,pb^1=18)}}}


{{{system(p=8,pb=18)}}}


{{{8*b=18}}}

{{{b=18/8}}}

{{{b=9/4}}}


{{{y=8*(9/4)^x}}}


{{{highlight(f(x)=8(9/4)^x)}}}
