The domain: D={-3;-2;-1; 1}
f(x) = -x + 4
subtitute
f(-3) = -(-3) + 4 = 3 + 4 = 7
f(-2) = -(-2) + 4 = 2 + 4 = 6
f(-1) = -(-1) + 4 = 1 + 4 = 5
f(1) = -1 + 4 = 3
Answer: The range: {3; 5; 6; 7}
Hello,
We can not divide by 0.
==> x+4.5≠0
==>x≠-4.5
dom f=R\{4.5}
So the height (h) of a cumulus cloud is at least (<u>></u>) 2100 feet (2100 feet)
h<u>></u>2100
at least means the least it can be is 2100 feet, and it can go more
This answer looks correct .
the 5 is canceled with the 2/5, therefore, leaving a 2 behind.
