Question

Find a polynomial function to model the data.



f(x) = 4.17x4 – 1.21x3 + 2.53x2 + 26.79x – 148.35

f(x) = –4.17x4 + 1.21x3 – 2.53x2 – 26.79x + 148.35

f(x) = –4.17x5 + 1.21x3 – 2.53x2 – 26.79x + 148.35

f(x) = –4.17x3 + 1.21x2 – 2.53x + 148.35

Answer 5

well I'd plot the data ... just running it table through my head I get


so it looks like a quartic...

given it starts lower on the left... I expect a negative quartic...

sorry but that's my best guess just looking at the data...

you could use this site

https://www.desmos.com/calculator

to plot the points in the table them plot the curves...

sorry its not a lot of help
