The function that does not have a range composed by real numbers less than or equal to 0 is given by:
d. f(x) = log(x - 3).
What is the range of a function?
The range of a function is the set that contains all possible output values for the function.
In this problem, we want a function without positive values as output.
We look at item d, in which the function is defined by:
f(x) = log(x - 3).
When x = 13, we have that:
f(13) = log(13 - 3) = log(10) = 1.
Which is a positive number, hence the function that does not have a range composed by real numbers less than or equal to 0 is given by:
d. f(x) = log(x - 3).
