Question

What is the range of y = log x + 2?

(2,∞)
[ 1,∞)
{ 2,∞)
(-∞,∞)

Answer 1

{ 2,∞) ? right ?

Answer 2

No guessing... and remember, it's *range* not domain...

Answer 3

the range is, -infi. , + infi. so, if we add 2..

Answer 4

woudn't it be a bracket ?

Answer 5

Range is the set of all numbers that y could possibly take... a simple way to do this is to try to isolate x... can you do that?

Answer 6

transpose? or change to exponential ?

Answer 7

change to exponential seems to work :)
