Regression Functions Using Real World Data (If you need to pass another work sample ONLY complete questions 1 -5 , review your work, and come to me when you are ready for your work sample.)
1) Select at least one set of data. Tell me what data you selected: ____________________.
2) Review enough of the links below to understand the assignment.
3) Using Desmos find the best fit function for: (Write the equations you found.)
Linear: y=mx+b
Quadratic: y=a(x-h)2+k
Exponential: y=a(b)(x-h)+k
Power: y=axb
4) Find a linear approximation by hand. Write your equations and show your method.
5) Find a quadratic approximation by hand. Write your equations and show your method. Consider the location of the zeros and write in factored form. Remember to find the “a” value. y=a(x-h)2+k
6) Find data that is a good fit for a quadratic function.
Tell me what data you selected: _______________. Equation Found: _______________.
7) Find data that is a good fit for an exponential function.
Tell me what data you selected: _______________. Equation Found: _______________.
