Consider the following function. f(x) = |x − 9| Find the derivative from the left at x = 9. If it does not exist, enter NONE. -1

nydimaria [60]

Answer with Step-by-step explanation:

We are given that

$f(x)=\mid x-9\mid$

$f(x)=-(x-9)$ when x<9

$f(x)=x-9$ when $x\geq 9$

LHD

$\lim_{x\rightarrow 9-}f'(x)$

= $-\lim_{x\rightarrow 9-}(x-9)=-1$

RHD

$\lim_{x\rightarrow 9+}f'(x)$

$=\lim_{x\rightarrow 9+}(x-9)=1$

$LHD\neq RHD$

Hence, the function is not differentiable at x=9

Pls halp list four nonzero multiples of 2 6 9 12 25 90

Simora [160]

Multiples of 2: 2,4,6,8

Multiples of 6:6,12,18,24

Multiples of 12:12,24,36,48

Multiples of 25:25,50,75,100

Further explanation:

A multiple is a number that is obtained by multiplying an integer with that number.

We have to find multiples of given numbers:

So,

1. Multiples of 2

$Four\ non-zero\ Multiples\ of\ 2: 2,4,6,8$

2. Multiples of 6

$Four\ non-zero\ Multiples\ of\ 6: 6,12,18,24$

3. Multiples of 12

$Four\ non-zero\ Multiples\ of\ 12: 12,24,36,48$

4. Multiples of 25

$Four\ non-zero\ Multiples\ of\ 25: 25,50,75,100$
