Dioxins are a class of long-lived and highly toxic pollutants.The topsoil concentration in parts per million (ppm)are shown in the table below as a function of distance from the dump.
Create an appropriate model to re-express the Concentration (ppm).Then use your model to predict the dioxin concentration at a distance of 400 metres.Round all figures to 4 decimal places.
A)3.56 ppm
B)3.9477 ppm
C)3.9196 ppm
D)3.8796 ppm
E)3.9714 ppm
