oh ok

y = aln(bx)

and you have two points it goes through

0 = aln(2b)
1 = aln(4b)

so you can solve these simultaneously

ln(2b) = 0
2b = 1
b = 1/2

1 = aln(2)
a = 1/ln(2)

It's only the top line which is missed off! which i just wrote...

ok so
Aln(2B)=0

ln(2B)=0 ln(1)=0

so b=0.5

then sub b into Aln(4B)=1
what exam broad is this
