The function f is given by f(x) = a.c, where a > 0 and c> 1. Which of the following is true about the values of constants m and b in the equation In (f(x)) = mx +b?
a. B m> 0 because In c> 0, b can be any real number because In a can be any real number.
b. m> 0 because In c> 0; b> 0 because In a > 0.
c. m can be any real number because In c can be any real number, b can be any real number because In a can be any real number.
d. m can be any real number because ln c can be any real number, b>0 because ln a>0
