Uhh me neither thats very complicated
        
                    
             
        
        
        
An exponential function can be expressed as:
y=ab^x  we have two points so we can solve
64/8=(ab^4)/(ab^1)
8=b^3
2=b, now we have:
y=a(2^x), using point (4,64)
64=a(2^4)
64=16a
4=a so
y=4(2^x)
