Question

What is the domain for the function f(x) = 2^(x-5)?
All Real Numbers
B. x > 0
C. x < 0
D. x > 1

Answer 1

the domain is all real numbers since for any x we put in the function we can get value for f(x) , we restrict some values of x from the domain usualy when x is under square root so we cant have negative numbers under square root or when it is in fraction we cant have 0 in denumerator .
