Answer:

The domain is all real numbers or (-infinity, +infinity)

The range is all numbers greater than or equal to 4 or (4,+infinity)

Hope this helped! :)

ANSWER

$(-∞,+∞)$

EXPLANATION

The given function is

$f(x) = {x}^{2} + 4$

This is a polynomial function.

Polynomial functions are defined for all real values of x.

For every x-value, there is a corresponding y-value.

Therefore the domain of the given function is all real numbers.

We can rewrite this as:

(-∞,+∞).

Answer:

The statement is false.

Step-by-step explanation:

If the modeling is with multiple variables it is necessary for all the variables to be modeled well such that the criticality of the model is dependent on all the variograms. It is not dependent on the cross variograms only.

Differentiate the function. f(x) = ln(25 sin^2(x))

tigry1 [53]

Use the chain rule.
Let u = 25sin²(x), such that dy/dx = dy/du · du/dx

$\frac{dy}{dx} = \frac{1}{25sin^{2}(x)} \cdot 50cos(x) \cdot sin(x)$
$\frac{dy}{dx} = \frac{2cos(x) sin(x)}{sin^{2}(x)}$

$\frac{dy}{dx} = 2cot(x)$
