Explanation / Answer

a) we have given V=IR and V=12 volts

If R=8,I=12/8

If R=8.1,I=12/8.1

So the average rate of change of I with respect to R is

((12/8)-(12/8.1))/(8-8.1)=-0.18518518518

average ROC=-0.18518518518

b) we have V=IR impliex I=V/R =12/R

dI/dt=-12R-2

when R=8

dI/dt=-12(8)-2=-12/64=-0.1875

ROC=-0.1875

c) we have V=IR implies R=V/I and V=12 volts

R=12/I

dR/dI =-12I-2

when I=1.7

dR/dI =-12*(1.7)-2=-12/(2.89) =-4.15224913495

ROC=-4.15224913495
