Which of the following statements about the values of the constants a, b, k, and n are true? Select all true statements and submit your answers A., b 1 B. a b D., k> 1 E. k

Solution

f(x) = ae^kx

e^x : a= 1 ; k =1

ae^kx ; a > 1   ; 0< k <1

be^(nx)

b >1 ; n = <0 ( as it is adecay equation)

a = b ( as both curve intersect at y axis)
