Respuesta :

The range of the function y = x is all real numbers.

Answer:

y ∈ {Real numbers}

Step-by-step explanation:

First try to establish the domain of the function i.e which x values can it it take and which ones can it not take. For example is there an x value that makes it contravene a sensible mathematical operation like diving by zero or taking the square root of negative number (which though possible isn't done in real numbers). This function takes any x value as long as it is a real number. And in turn it gives all kinds of y values from negative infinity to positive infinity. So the range of this function is all real numbers
