Question

I got C. Am I correct?! :P

Which logarithmic graph can be used to approximate the value of y in the equation 2y = 3?

Answer 1

Hints:
\(2^y = 3\) can be expressed also as \(y=log_2(3)\).
So you're looking for a graph corresponding to logarithm of log to the base 2.

Answer 2

yes.
the graphs have shapes
y= log(x)
you want the curve for
y = log_2 (x) (log base 2)
and you know log_2(2) is 1
so you want the curve that contains the point (2,1)

Answer 3

btw, you should write your equation as
2^y =3
(2y really means 2 times y)

Answer 4

Yes sorry abt dat.
I would be getting A. then.

Answer 5

how would you get choice A ?
the last graph shows the curve at y=1 when x=2

Answer 6

Sorry I was looking at the wrong graph >.< Thx
