Question

What are the equalities of f(x)=loga(x)

A. f(1)=0
B. f(a)= 1
C. f(0)=0
D. f(1/a)=-1
​

Answer 1

9514 1404 393

Answer:

A, B, D

Explanation:

For appropriate values of 'a', the log function has the following characteristics:

• A: f(1) = 0
• B: f(a) = 1
• D: f(1/a) = -1

Any log function will tend toward negative infinity as x tends to zero (for |a|>1).
