Place value. when multiplying by 10 you are moving a decimal, having everything lined up like place value would save you a lot of time.
If graphed correctly the x-axis will always have the independent variables
F(x) = (1/x) + ln x
At the extreme values, f'(x) = 0
f'(x) = -1/x^2 + 1/x = 0
(x - 1)/x^2 = 0
x - 1 = 0
x = 1
f(1) = 1/1 + ln 1 = 1
Therefore, the extereme value is 1 and occurs at x = 1.
C is the answer because its longer and a big number sentence
