Fill in the blank: when using the least squares method, the line of best fit is the line that

a- minimizes the total area of error squares on the scatter plot
b- minimizes the sum of the squared deviations of the data points from the line
c- both a and b
d- none of the above

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
