X 0 0.5 1.5 2 3 4 5
Y 0.32 2.6 7.05 11.74 15.83 22.3 25.9
a) Plot the data in the above table as 'diamonds' (not connected by line).
b) Obtain the best fitting line to the data. (Write the equation on this paper).
c) Add to the previous figure a plot of the best fitting line. Use more data points for this plot. Use x values ranging from 0 to 5 in a step of 0.1. This curve must be a line (without symbols).
d) Add grid to the plot.

Give it a go yourself this time.
You will need to read the plot, polyfit, polyval, and Colon(:) documentation.

I imagine it's like the demo in the help but maybe a bit fancier. See attached demo (below the image it creates) that I've posted before. Adapt as needed.
