AS A MATTER OF FACT FOR THE DOMAIN WE CAN SEE IN THE EQUATION THAT THERE IS NO RESTRICTION OF X THAT CAN MAKE THE WHOLE EQUATION UNDEFINED

DOMAIN X CAN BE ALL REAL NUMBERS.

NO MATTER THE VALUE OF X YOU INSERT IT WILL ALWAYS TURN POSITIVE PLUS A POSTIVE TWO. MEANING THERE IS NO WAY THAT YOUR Y CAN BE EQUAL TO 0 OR A NEGATIVE NUMBER THE FUNCTION IS ALWAYSINCREASING FOR ANY VALUE OF Y.

RANGE: Y IS ALL THE REAL NUMBERS GREATER THAN 0.
