question 31

Multiple Choice

-

• A) Logistic, \(f ( x ) = \frac { a } { 1 + b e ^ { - k x } }\)
• B) Exponential, \(\mathrm { f } ( \mathrm { x } ) = a b ^ { - \mathrm { x } }\) or \(\mathrm { f } ( \mathrm { x } ) = \mathrm { P } _ { 0 } \mathrm { e } ^ { - \mathrm { kx } } , \mathrm { k } > 0\)
• C) Quadratic, \(f ( x ) = a x ^ { 2 } + b x + c\)
• D) Polynomial, not quadratic
