# Math Help - Help with functions? Please?

1. ## 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 $c\in \mathbb{R} /\{2\}$

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

3. Yes, I actually just figured out how to do it, and I got the right answer.
