what is the domain of h(x)=29 over x+6

Question

I am having trouble finding the domain and range of equations.

Answer 1

The domain is all possible input values of x

 

With h(x)  = 29/(x+6)

the only restriction is that we cannot

divide by 0.  The only restriction is that

the denominator cannot be zero, so

x cannot equal 6.  All other values

of x are acceptable.

 

D = (-∞, 6)U(6, ∞)

 

The open parenthesis indicates the

value next to it is not included in 

the answer.
