See explanation

Explanation:

The function 6/(x+3)6x+3 will have a restricted domain at x=-3x=3.

We know this because the denominator of our function cannot be 00 and to find what value this occurs, we set the denominator equal to 00 such that:

x+3=0 -> x=-3x+3=0x=3

What this tells us that the graph will have a vertical asymptote at x=-3x=3

Thus our domain for this function is: {x| x!= -3} or (-oo,-3) uu (-3,oo){xx3}or(,3)(3,)
