To find: the equation of the given parabola two different ways, by hand and with technology. Write a paragraph describing the method by hand and comparing the result.

Answer to Problem 83E
Equation of parabola is
Explanation of Solution
Given information: The given parabola has an equation of the form
Calculation:
Pick two of the points such as (1,0) and (4,0) to make a system of equation with 2 unknowns.
Putting the value of a=- 1 and b =5, the equation of parabola is,
A “graphing utility “gives the exact same result.
By hand had to solve a system of equations with 2 unknowns which is easy because normally there would be 3 unknowns as c =-4 was given already. For the “graphing utility” all have to do is enter the points one by one then ask for a “quadratic fit” or “fit polynomial with degree 2 “.Usually the “graphing utility” method is easier.
