Let lim x→a g(x) = 1 , lim x→a f(x) = 0, lim x→a h(x) = 7. find following limits if they exist. if not, enter dne (’does not exist’) as your answer.
1. lim x→a (g(x) + f(x)) 2. lim x→a (g(x)− f(x)) 3. lim x→a (g(x) ∗ h(x)) 4. lim x→a g(x) f(x) 5. lim x→a g(x) h(x) 6. lim x→a h(x) g(x) 7. lim x→a p f(x) 8. lim x→a f(x) −1 9. lim x→a 1 f(x)−h(x)
