1.6.8 Reduction to linear form

Card 1 of 23

For y=axny=ax^ny=axn, what should be plotted to obtain a straight line?

A

For positive uuu and vvv, log⁡(uv)=log⁡u+log⁡v\boxed{\log(uv)=\log u+\log v}log(uv)=logu+logv​.

B

The logarithm power rule is log⁡(ur)=rlog⁡u\boxed{\log(u^r)=r\log u}log(ur)=rlogu​.

C

Plot log⁡y\log ylogy against log⁡x\log xlogx.

D

The model may be unsuitable.
