The y axis is from 0 to 15000 and the x axis is from 0 to 4. I know by default the plots should be in exponential format, however the first 4 subplots are not but the rest are. Why is this happening? Recall that a variable y satisfies exponential growth if it satisfies the differential equation y ' = k * y (where k > 0). The solution to this differential equation is y = C * e^ ( k * t ), where C represents the initial value of y at time t = 0. Typically the value of k is found from knowing the value of y at some other time t.The toolbox provides a one-term and a two-term exponential model as given by. y = a e b x y = a e b x + c e d x.
