what graphs

anonymous · Answer

you have to graph the answer choices

anonymous · Answer

None of these are exponential decay, although 
y=1/(4x)  does decrease with a power law exponent of -1.
the others increase.

thats what i got but i thought that i was wrong but thanks for the help

anonymous · Answer

You are welcome. Usually, exponential decay is y=exp(-k x).
