Graph

100

y=ln(x+4)-2

left 4, down 2

200

y=ln(x-2/3)-1

right 2/3, down -1

300

y=-1/2log(x+2)-4

left 2, down 4, vertical compression, reflected across x-axis

400

y=-4log(-5x+20)

as x is -infinity, y is -infinity and as x is 4, y is infinity

500

4log(x)

as x is 0, y is - infinity and as x is infinity, y is infinity
