Quadratic Equations By: Tate simpson and gerrit meine

Point A (-4,5) Point B (-3,3) Point C (-2,2) Point D (2,2) Point E (4,4)

I used these points to calculate my regression line in my calculator. y= .21x^2-.083x+1.093

I used my regression equation to predict the height of the parabola when x=3 on my coordinate plan. y= .21(3)^2-.083(3) +1.093 (3,2.734)

x^2+8x-20
