y=2%5Ex

graph%28200%2C400%2C-6%2C4%2C-1%2C18%2C2%5Ex%29

That's increasing because it goes up to the right.

y=%281%2F2%29%5Ex

graph%28200%2C400%2C-4%2C6%2C-1%2C18%2C.5%5Ex%29

That's decreasing because it goes down to the right.

y=log%282%2Cx%29

graph%28200%2C400%2C-4%2C6%2C-9%2C9%2Clog%282%2Cx%29%29

That's increasing because it goes up to the right.

y=log%281%2F2%2Cx%29

graph%28200%2C400%2C-4%2C6%2C-9%2C9%2Clog%281%2F2%2Cx%29%29

That's decreasing because it goes down to the right.
