What is the domain of the function y = l n (x + 2)
x less-than negative 2
x greater-than negative 2
x less-than 2
x greater-than 2

Respuesta :

x greater than negative 2, because ln(x) is undefined for x <= 0 (-2+2=0, -1.999...+2>0)

The domain of a function is the input values for which the function exist. The domain of the function y = l n (x + 2) is x greater-than negative 2

How to calculate the domain of a function?

The domain of a function is the input values for which the function exists

Given the function

y = ln(x+2)

The function can only exist at the point where x + 2 is greater than zero. Hence:

x + 2 > 0

x > -2

Hence the domain of the function y = l n (x + 2) is x greater-than negative 2
