What is the range of the function $f(x) = 3- 2\cdot 51^x$? Give your answer as an interval.

-1

If  x  is   "very negative," the second trem will go to 0  and the range max  will be  almost 3

 

If x is "very postive,"    the  function  will approach  -inf

 

So the range is    (-inf, 3)

Thank you so much!!

 

Hey CPhill I have one more quick question:

 

Suppose $81^x = 64$ What is $27^{x+1}$?
