I need some help with infinity norm proofs for a matrix
Please find the problem in the attachment because I couldn't figure out how to write the math formulas here.

Thanks

Hey EmilyC123.

One suggestion I have is to show that since the system is continuous then it belongs to a Banach space and then use the Banach-Norm inequality to justify the condition.

Chiro,

Thanks for your reply, but I'm not familiar with the Banach Norm.
I don't think my prof. would give me a problem that needs to be solved with material he hasn't taught in class. I think the problem needs to be solved with what is given. The problem is that I can't figure how to connect equations 1 and 2.

If you have any more ideas please let me know.
