For the scatterplot on the right, determine which, if any, of these functions might be used as a model for the data. Quadratic f(x) = ax + bx + c Polynomial, not quadratic # of fruit flies (hundreds) Exponential f(x)= a ex, k>0 Exponential f(x) = ae kX k>0 a Logarithmic f(x) = a + binx Logistic: f(X) = 1+be - kx 1 2 4 5 X Day try Which of the functions above might be used as a model for the data? A. Exponential: f(x) = aex, k>0 21 O B. Polynomial, not quadratic O C. Exponential: f(x)= ae -X, k> 0 O D. Quadratic f(x) = ax2 + bx + c O E. Logarithmic. f(x) = a + b Inx a OF. Logistic: f(x) =- 1 +be - kx
