suppose that we have following problem suppose that ball is dropped from upper observation deck of the CN tower,450 meter from the ground,and distance h is given in 1 second interval
0 450 1 445 2 431 3 408 4 375 5 372 6 279 7 216 8 143 9 61
this is problem taken from calculus book,as graph was given it was clear that linear model was not suitable,so author choosed quadratic model i have tried to get the same result as author had which is expressed like this
but when i have wrote quadratic form
y=a*x^2+b*x+c and put first three x values,got
y=-4.5*x^2+0.5*x+450 i am interested how accurate and correct it is?
