Find a quadratic model for the set of values: (-2, -20), (0, -4), (4,-20) show your work

For this case, the quadratic function in its generic form is given by:

We must find the values of the coefficients.

For this, we evaluate the given points.

For (0, -4):

For (-2, -20):

For (4, -20):

Therefore, for the values of a and b we have the following system of equations:

Resolving graphically (see attached image) we have:

Then, the quadratic model is:

a quadratic model for the set of values is:

1/800 is the right answer
