Use the quadratic model to predict the exam score for someone who works 100 problems

Answer 1

do you have more specifics as to what the parameters are for the quadratic model? basically the idea is that you would be plugging in x = 100 into the equation ... so since it's a quadratic it should be something like

y = ax^2 + bx + c for the general form

and then you would be plugging in x = 100 into that equation

y = a(100)^2 + b(100) + c and simplifying it down based on the values of the coefficients

Answer 2

For this question we would use the quadratic equation: 𝑦=𝑎𝑥^2+𝑏𝑥+𝑐 where "𝑦" represents the exam score and "𝑥" represents the number of problems worked, 𝑎,𝑏, and c are constants based on the data. The data points would be number of problems worked as your "x" and corresponding exam scores being your "y", you can use those to determine the values of 𝑎,𝑏, and c. Once the quadratic model is established, you can plug in 𝑥=100 (the number of problems worked) to predict the exam score.
