#x inRR, x!=-8/3#

Explanation:

The only time #n(t)# will be undefined is when our denominator is equal to zero, as we know that we cannot divide by zero.

Let's just set the denominator equal to zero. We have

#3t+8=0#

Subtracting #8# from both sides, we get

#3t=-8#

Dividing both sides by #3#, we get

#t=-8/3#

This is the only value that #n(t)# is undefined, thus or domain is

#x inRR, x!=-8/3#

Hope this helps!
