Question

Solve: y=e^x - 4

Answer 1

is it \(y=e^x -4\)? or \(y=e^{x-4}\)?

Answer 2

ooh sorry, um its the 1st one

Answer 3

First you set y=0; 0=e^x-4

Add 4 to both sides

4=e^x

do the natural log of both sides

ln4=ln(e^x)

know: ln(e^x)=x*ln(e)

ln(e)=1

therefore:

ln4=x*1

x=ln(4)

Answer 4

ooh thank you
