Using the same approach as was employed to derive Eqs. (17.15) and (17.16), derive the least-squares fit
Question:
Using the same approach as was employed to derive Eqs. (17.15) and (17.16), derive the least-squares fit of the following model:
y = α1x + α2x2 + e
That is, determine the coefficients that results in the least-squares fit for a second-order polynomial with a zero intercept. Test the approach by using it to fit the data from Prob. 17.26.

I have done job as Embedded System Engineer for just four months but after it i have decided to open my own lab and to work on projects that i can launch my own product in market. I work on different softwares like Proteus, Mikroc to program Embedded Systems. My basic work is on Embedded Systems. I have skills in Autocad, Proteus, C++, C programming and i love to share these skills to other to enhance my knowledge too.
