Question

PLEASE HELP!!! I don't know how to write this in interval notation....I'll post the problem below

Answer 1

for x>4 use (4,+∞)

for x>-4 use (-4,+∞)

If you want to include a number use this symbol [ or ] If you don't want include the number use this symbol ( or )

Answer 2

I guess the web site doesn't like asci characters. The ? marks is just an infinity symbol.
