I have included a graph to help you see what the domain and range would be
There are no minus y values.
0<y< infinity y is included in the reals.
The domain is
- infinity < x < infinity.
I don't want to say that either x or y can equal - or + infinity. Some teachers allow it. You have to ask your instructor what they will accept.
The blue line is y = 4^x
The red line is y = 2^x
21 x 9 = 9 x 21 is the commutative property.
Hey!

Switch it around and it becomes:

First find 18 ÷ -6

Positive ÷ negative OR negative ÷ positive is always negative.
That leaves you with:

Switch that around and it becomes:

Find -3 + 5

That leaves you with:

Divide both sides by 2 to leave <em>x</em> alone
