Use the chain rule:
We have
so we get
Alternatively, you can substitute <em>u</em> in the definition of <em>y</em> and differentiate with respect to <em>x</em> :

Answer: 2.3</h3>
The absolute value of any positive number is that number itself.
If you take the absolute value of a negative number, then just erase the negative sign and you have your answer.
The absolute value is never negative. It represents distance from that value to 0 on the number line.
So saying |2.3| = 2.3 means the number 2.3 is exactly 2.3 units away from 0 on the number line.
Another example would be |-7| = 7 showing that from 0 to -7 is 7 spaces.
The two trains the same distance from Buffalo is 20
Annual = $68,000
Semiannual = $34,000
Monthly = $5,666.67
Semimonthly or bimonthly = $2,833.33
Weekly = $1,416.67
-1/1 because it goes to the left once and up once so it will be one over one but it’s one the left side so it will turn negative so it will be negative one over one
