Using the quotient rule
f'(x) = x * 1/x - ln x 1 - ln x
----------------- = --------- <-------- ur answer
x^2 x^2
Side angle side the answer hope that helps
-1 * (-4) = 4; 3 * (-4) = -12; 6 * (-4) = -24; -3 * (-4) = 12
Answer:
Step-by-step explanation:
The equation shown in the question can be seen graphed in the image attached below. As you can see with the graphed equation the variable x can be any real number except for -1. This is because a -1 would cause the denominator of the fraction to be equal to 0, and a fraction with a denominator as 0 is a null value and does not exist.
