Use your calculator to create a formula for the model you have chosen. Enter the ordered pairs into lists and have the calculator create the best fit function for your model. For example, if your path appears to be exponential, you will have a model of the form y = abt using the ExpReg feature on the calculator. If you think the function is quadratic your model will have the form y = at2 + bt + c using the QuadReg feature on the calculator. You will then do the same for x. You do not have to use the same model type for both x and y. Pick the model that fits each one best! Remember do not use a linear function!

Question

Directions to create this model on the TI84Plus or Desmos Calculator are at end of portfolio.

d. Write your final equations: (2 points)

x(t) =

y(t) =

Answer 1

x(t) = 5.3t^2 - 2.7t + 0.8

y(t) = 2.1t^2 - 1.4t + 0.6
