Question

What is the range of Y=log, X?

O all real numbers less than 0
all real numbers greater than 0
all real numbers not equal to 0
all real numbers

Answer 1

Option 4 - All real numbers

Explanation:

The range of a function is defined as all possible y-values for the function.

You can rewrite the equation
`\log_b(x)=y` as
`$b^y=x`. So
`$y=\log_8(x)\Rightarrow 8^y=x$`.

Based on this equation you can plug in any real number for y and the equation will still be valid, so option 4 is correct.
