I was wondering,
1.how do we find the range of a function w/o a calculator?
2. how do we know if its this bracket () or this bracket ? what will determine it.
(0,5) means all numbers between 0 and 5 but not including 0 and 5.
[0,5] means all numbers between 0 and 5 including 0 and 5.
Yeah, I was trying to work out this problem g(x) = sqrt(16-x^4)...i found the domain to be x=+-2
but I could not figure out the range...
also, how would I know which bracket to use? in this case, since x cannot be -2 or +2 should I use () meaning not to include -2 or +2?
