The output of log is highly dependent upon the value of a or base If value of a is grater than one and the value of input is greater than one We will get positive values And if the values of a is more than one and value of input is less than one(excluding negative and zero) we get negative values Vice versa If values of a is less than one and value of input is more than one We will get negative values And is value of a is less than one and value is also less then one(excluding negative and zero)we get positive values

Ans of the HW: In a logarithmic function, f(x)=log x with base a The output y is negative when the base a or the input x or both are less than 1 & The output is positive when both the input x as well as base a is more than 1 or equal to 1. Love you SiR❤💜🧡💛💚💙

When the base is less than 1 then the value of y become 1. So, base is greater than 1 or x is less than 1.

For log(x), x being any number, log(x)=0 if x=1. For values less than 1, it gives negative. Example, log(100) taking base 10 is 2. This is positive. If we take 0.1( which is 10 to the power -1), we get log(0.1)=-1. So if the number is proper fraction,ie: it lies between 0 and 1, logarithm is negative. Anothe example, For base 2,log(0.25)=-2 because 0.25= 2^-2. This is genaralized as for 0

Jab base 1 se bada hoga aur chota aur input bhi bada hoga air chota respectively tab output negative hoga. In short for negative output (bada,chota ),(chota bada ) Positive (bada ,bada ),(chota bada ) Bada means more than 1 Chota means less than 1 and more than zero.
