Question

What is the domain of the function y=3 in x graphed below?

Answer 1

Answer:

domain is x>0

Step-by-step explanation:

$y=3ln(x)$

domain is the set of x values for which the function is defined

ln(negative value ) is undefined

So we take positive values for x because we have ln(x)

From the graph we can see that the given equation has a graph for x values greater than 0

the graph goes close to 0 but does not crosses y axis

So domain is x>0

Answer 2

What is the domain of the function y=3 in x graphed below?

Domain is x>0, ln (0) is undefined and there is no negative ln.
