f(x) is a piecewise function defined as:
[tex]3\pi x-4 x>=1[/tex]
Discuss the continuity of f(x) at x=1.
The Attempt at a Solution
Putting x=1 in the above function gives you 2e and [tex]3\pi -4[/tex]. They seem to be equal, but how do I prove it mathematically? I've missed something here, but don't know what.
