What is the range of the function $f(x) = 3- 2\cdot 51^x$? Give your answer as an interval.
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 $27^{x+1}$?
