F(x)=2x and g(x)=square root of x what is the domain of f(g(x))?
Dmitriy789 [7]

Answer:

x\ge 0

Step-by-step explanation:

The given functions are:

f(x)=2x


and


g(x)=\sqrt{x}


Now,

f(g(x))=f(\sqrt{x} )


f(g(x))=2\sqrt{x}

The domain refers to values of x for which f(g(x))=2\sqrt{x} is defined.


The  expression under the radical sign must not be negative.

The domain is

x\ge 0

An analyst must decide between two different forecasting techniques for weekly sales of roller blades: a linear trend equation a
Amiraneli [1.4K]

Answer:

Following are the responses to the given question:

Step-by-step explanation:

Mean Absolute Deviation MAD

MAD = \sum_{i=1}^{n} \frac{\left | actual_{i}-forecast_{i} \right |}{n}

Mean squared error  

MSE=\Sigma^{n}_{i=1} \frac{(Actual_i - Forecast_i)^2}{(n - 1)}

linear trend equation is Ft = 124 + 2t

MAD = \frac{23}{10} = 2.3\\\\MSE = \frac{91}{9}= 10.11\\\\

Naive method

MAD = \frac{36}{9} = 4\\\\MSE = \frac{202}{8}=25.25\\\\MAD (Naive) = 4\\\\MAD (Linear) =2.3\\\\MSE (Naive)=25.25\\\\MSE (Linear)=10.11\\\\
