This is not a multiple choice answer. You have to substitute the numbers given to the equation.
x=4
y=log(4)
y=log(2^2)
y=2log(2)
Use identity: logb^c = c x logb
x=0.25
y=log(0.25)
y=log(1/4)
y=log(1/2^2)
y=log(2^-2)
y=-2log(2)
x=0
Log is undefined
x=75
I’m not sure with this one. But if you put it in a calculator, you get 1.8751
If you find the derivative, it is 0, but I’m sure that it is not what you are looking for since you are only in algebra II.
Answers again: y=2log(2), y=-2log(2), undefined, and 1.8751
