Thread: Help with functions? Please?

Determine whether f is continuous at x = c in the function given below. Use the 3 conditions of continuity to justify your answer.

f(x) = :
(x - 1, if x < 2),
(2, if x = 2),
(2x, if x > 2)


Any help is appreciated.

Given the question I would say

You really need to graph this function. Have you done this?

Yes, I actually just figured out how to do it, and I got the right answer.
Thank you for replying.
