Multiple Choice

Choose the function that might be used as a model for the data in the scatter plot.
-

A) Polynomial, not quadratic
B) Exponential, $\mathrm { f } ( \mathrm { x } ) = a \mathrm {~b} ^ { \mathrm { x } }$ or $\mathrm { f } ( \mathrm { x } ) = \mathrm { P } _ { 0 } \mathrm { e } ^ { \mathrm { kx } } , \mathrm { k } > 0$
C) Logistic, $f ( x ) = \frac { a } { 1 + b e ^ { - k x } }$
D) Logarithmic, $f ( x ) = a + b \ln x$
