Question

For what values of the variables are the following expressions defined? 18/y

Answer 1

Answer:

y ≠ 0

Step-by-step explanation:

y ≠ 0

to determine a rational number, the denominator must not be zero.

Answer 2

The values of the variable 18/y are defined for all the values of y, such that y is the element of real numbers (R), y ≠ 0

What is a function?

A function is defined as the relationship between a specific set of inputs assigned to one output each.

In order to determine if a function is defined, we need to determine the values that make the function undefined and eliminate it.

From the given information:

• The value that makes 18/y undefined is any value that makes y = 0

Therefore, we can conclude that 18/y is defined for all the values of y, such that y is the element of real numbers (R), y ≠ 0
