Question
I DON’T KNOW IF MY ANSWERS ARE CORRECT OR WRONG?
If a function f(x) is not defined at x = a, then the limit of f(x) as x approaches a never exists. Time Select one: O True O False If lim, ya f(x) = lim, »a f(x) , then lim, ya f(x) does not exist. Select one: O True O False If lim, ra f(x) is not equal to f(a), thenf is discontinuous at x = a. Select one: O True O False The function f(x) = 2/(x-5) is continuous on the interval (0, 5). Select one: O True O False The function f(x) = 2/(x² + 4) is continuous at any real number. Select one: O True O False
