You are told only two things about a pair of functions:
limx→4f(x)=6andlimx→4g(x)=−2\lim_{x \to 4} f(x) = 6 \qquad \text{and} \qquad \lim_{x \to 4} g(x) = -2limx→4f(x)=6andlimx→4g(x)=−2
You never see the formulas for fff or ggg themselves.
Using the limit laws, evaluate
limx→43f(x)+[g(x)]2f(x)−g(x)\lim_{x \to 4} \frac{3f(x) + \left[g(x)\right]^2}{f(x) - g(x)}limx→4f(x)−g(x)3f(x)+[g(x)]2
Select all that apply.
