Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = x2 − 5x x2 − 25 if x ≠ 5 1 if x = 5 a = 5

For to be continuous at , we need to have



Note that means that , but that is *approaching* 5. We're told that for , we have



We can write



and the limit would be



and so is discontinuous.

Cd is the perpendicular bisector of both xy and st, and cy=20.find xy

Dbecause there are negatives surrounding ding it
