Question

with an exponential transformation, how does the data set (x, y) change?

a) (log x, y)
b) (x, log y)
c) (log x, log y)
d) cannot be determined without a data set

Answer 1

You tell me. Under which of those given transformation is an exponential relationship turned into a nice, linear relationship. The right answer IS given.

Answer 2

I think its d but I don't know for sure

Answer 3

I just told you it wasn't d. Ponder it. What happens if you apply a logarithm to the x-values? What happens if you apply a logarithm to the y-values?

Answer 4

Transforming both is unlikely to be beneficial.

Answer 5

my dad said to change the transformation you have to change y...is he correct?

Answer 6

Here's a data set.
x y
0 1
1 2
2 4
3 8
4 16
5 32

If we take logs, base 2 on the y-values, we get

x y
0 0
1 1
2 2
3 3
4 4
5 5

Well, that's a pretty convenient relationship, isn't it?

Let's go with your dad on this one.
