Question

Which of the following statements is true?

An exponential function is the inverse of a logarithmic function.

The base of the logarithmic function f(x) = log5x is unknown.

The range of the logarithmic function f(x) = log5x is all real numbers less than zero.

The domain of the logarithmic function f(x) = log5x is all real numbers.

Answer 1

d

Answer 2

the domain?

Answer 3

yes..

Answer 4

yea the last one

Answer 5

thxxxx

Answer 6

uhh no...

Answer 7

then which one is it? lol

Answer 8

the domain is not all real numbers

Answer 9

the domain of log_5 x is x>0

the base of log_5 x is known...it is 5

the range of log_5 x is im not sure but i know it's not x<0

Answer 10

so what does that leave?

Answer 11

the range is all reals...same as the domain of the exponential function

Answer 12

ohh yeah...5^x = y

Answer 13

i mean 5^y = x...
