hi i'm really struggling with this and its due later today! If someone could show the work of how to do it and the answer that would be really appreciated!!

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

Ineed to know the ordered pairs for this equation i need the answer quick because it’s a timed test

When steve woke up. his temperature was 102 degrees f. two hours later it was 3 degrees lower. what was his temperature then?
