Consider the function f defined by f(x) = 8^x
how do i find the domain and range of f?
-----
Domain: Can you think of any value x cannot take?
Neither can I.
So the domain is "All Real Numbers".
----------------
Range: Raising 8 to any power will never give you zero or a negative number.
So the range is "All Real Numbers > zero".
