Pressure and Volume -- are the growth/decay rates exponential?

[lee123456789]

Homework Statement

forumlate if its growth/decay is exponential
I have equation that i intergrated and found Pressure over volume = work done of pressure
P = 3.2c^-1.4
f(v) = -8v^-0.4
i set limits of 10x10^-6 --> 100x10^-6
and
10x10^-6 --> 100x10^-6 but i increase both values by 20x10^-6 every time for this one

Homework Equations

The Attempt at a Solution

i know they both decay and decrease in value by ruffly a half each time. but they slow down in decay and there decay rates slow down.
i know a exponential function is something power of x

second limits sets it doesn't cross the x-axis it stays just above it each time
first limits sets cross the x-axis and slows down but keeps on decreasing . it doesn't stay above a certain value. it keeps on decreasing

slightly confused
are these decay and is the function overall both examples exponential and exponential decay ?

Hello 1through9,

P = 3.2c^-1.4
f(v) = -8v^-0.4

This is not a problem statement. This way, helping becomes impossible !

Please write down the question. I cannot even guess why there is exponential decay to begin with.

forumulate if the decay/growth is exponential that is al lthe question has given

im just bit confused of expnential
i worked out and draw both grapth. one goes negative and one stays positive and just continuous hovers above the 0 mark of x axis. they both produce a curve. but one. but one of them continously decrease in valuve and never levels off
are these decay and is the function overall both examples exponential and exponential decay ?

Can't believe that. Is it about Little Red Riding Hood or is it about something else ? What ? Any context ?
