Question 80023: I need help writing a quadratic function using 3 out of these 5 points on a parabola. Can you help me please? (0,254)(4,234)(8,235)(12,239)(16,255)
Thank You

You can put this solution on YOUR website! Pick any of the three points.
Substitute their x,y values one at a time into the form y=ax^2+bx+c
You will get three equations with the three unknowns a,b, and c.
Solve the system of three equations for a, b, and c.
