## Homework Statement

In a certain experiment, the power (P) radiated by a light bulb filament was measured as a function of the filament's absolute temperature (T).

Data:

P(W)

0.45

0.95

1.8

3.5

5.6

T(K)

1000

1200

1500

1800

2000

(a) Plot the data (Done)

**(b) Assume a power function and re-plot the data.**

## Homework Equations

Unsure.

## The Attempt at a Solution

I plotted the data and it looks like a natural logarithm. I'm not sure what to do next. Raising each T value to the power of 2 straightens out the curve a bit but not completely. Is that what it means to assume a power function? If a power function is y=kx^a, how do I know which exact a to take and where do I get k from? Thanks.
