Final answer:
The range of a function depends on its definition and constraints. Option (A) is correct.
Step-by-step explanation:
The range of a function is the set of all possible values that the function can output. To find the range, we need to determine the possible values of y for a given x. Let's go through each option:
a. y = x - 5
The range of this function is all real numbers, as any value of x will result in a unique value of y.
b. Y = N X + 5
There seems to be a typo in this option as it does not define the equation. It is unclear what N and X represent, so we cannot determine the range.
c. y = x + 5
Similar to option a, the range of this function is all real numbers.
d. y = n/x - 5
The range of this function depends on the domain of x and the value of the constant n. Without further information, we cannot determine the range.
Therefore, the options with a definite range are a. y = x - 5
