Step-by-step explanation:
We say that a function is differentiable if it's derivative exists and it is continous over the domain of the original function. Recall that the function |x| is given as |x| = x if and |x|=-x if x<0. In both cases, we have either the function x or -x, which are one-degree polynomials. So, we can find easily their derivatives. So if f(x) = |x|. Then, we have that
We should check what happens x=0, since that is the point where the definition of f changes. We can check that
and
since this limits are not equal, the derivative is not continous at x=0. Hence, the derivative doesn't exist at x=0.
In this case, we say that |x| is differentiable at any x different from 0.
Answer:
135.58 just did this
Step-by-step explanation:
First, I calculated the amount of money he got on Monday. I multiplied. 8.50 x 7 which equals 59.50. Then, I calculated the amount of money he got on Tuesday. I multiplied 8.50 (since that is the number of money he gets paid) to 3.2 (since that’s the amount of hours he works). I got 27.200. Then lastly, I calculated the amount of money he got on Friday. So first I changed 5 3/4 into a decimal. This is 5.75. After, I multiplied 8.50 x 5.75, and got 48.8750.lastly, I added and got 135.575. So if you round it, it will be 135.58
