If f(x)= sqrtx-3 and g(x)=1-x^2, then what do you notice about the domain of (fxg)(x)?

  if  

  if  

Step-by-step explanation:

If   then the domain of f(x) is all positive real numbers. This is

On the other hand the domain of g(x) would be all real numbers because it is a polynomial function

Therefore

Then the domain of will be the same domain of

All positive real numbers,   or x ∈ [0, ∞)

If f(x) = then the domain of f(x) is

Therefore

Then the domain of will be the same domain of

or x ∈ [3, ∞)
