POLYNOMIAL CURVE FITTING
This is used when there are given points and you need to find the polynomial to see the whole graph..
1st find the system of the polynomial by substituting points to
y= a(sub 0)+a(sub1)x + a(sub2) x^2 +a(sub3) x^3+.......a(subn)x^n
the number of points minus one determine the highest degree you of x in
y= a(sub 0)+a(sub1)x + a(sub2) x^2 +a(sub3) x^3+.......
solve using any methos you want to find a(sub 0),a(sub1),a(sub2),a(sub3)...a(subn)
after you find those values... write it in the form of p(x)..
like this given
a(sub 0)=12
a(sub1)=2
a(sub2)=3
a(sub3)=5
p(x)= 12+2x + 3x^2 +5x^3 so this is the polynomial function
