What are the domain and range of f(x) = 2|x – 4|? domain: x <= 2; range: (-infinity,infinity) domain: (-infinity,infinity); r

s344n2d4d5 [400]

Answer:

domain: (-infinity,infinity);

range: f(x)>= 0

Step-by-step explanation:

f(x) = 2|x – 4|

The domain is the input values or the values that x can take

We can use any value we want for x

Domain: -infinity to infinity

The range is the output values

Since it is an absolute value, the smallest value it can take is 0, it can increase as large as it wants

Range: 0, infinity

For a given data group, simple exponential smoothing is being used to forecast demand. The forecast of a given period is 110, wh

Answer:

The smoothing constant alpha is 0.20 (Option a)

Step-by-step explanation:

To solve this problem, first we write the succession of the simple exponential smoothing:

$s_t=\alpha x_t+(1-\alpha)s_{t-1}$

Where s(t) is the forecast for period t, s(t-1) is the forecast for period (t-1), xt is the real demand for period t, and alpha is the smoothing constant.

All but the alpha constant are known

s(t)=109.2

s(t-2)=110

xt=110-4=106

Then, we can calculate alpha as:

$s_t=\alpha x_t+(1-\alpha)s_{t-1}\\\\109.2=\alpha*106+(1-\alpha)*110\\\\109.2=(106-110)\alpha+110\\\\(110-106)\alpha=110-109.2=0.8\\\\4\alpha=0.8\\\\\alpha=0.2$
