Define f(x)=1x+1f(x)=\dfrac{1}{x+1} and g(x)=3−xg(x)=\sqrt{3-x}. Consider the function h(x)=f(x)+g(x)f(x)g(x).h(x)=\frac{f(x)+g(x)}{f(x)g(x)}. The domain of hh is a) (−∞,3)(-\infty,3) b) (−∞,−1)∪(−1,3](-\infty,-1)\cup(-1,3] c) (−∞,−1)∪(−1,∞)(-\infty,-1)\cup(-1,\infty) d) (−∞,−1)∪(−1,3)(-\infty,-1)\cup(-1,3)
