What is the domain of the function? x + 3 f(x) = VX + 3

ahrayia [7]

Your question is a little ambiguous, but I am assuming that you meant to say the function $f(x) = x+3$

Thus, I am solving your question based on assuming the function such as

$f(x)=x+3$

But, it would still clear your concept, no matter what the function is.

Answer:

we conclude that

$\mathrm{Domain\:of\:}\:x+3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

The graph is also attached.

Step-by-step explanation:

Given the function

$f(x)=x+3$

We know that the domain of a function is the set of input or argument values for which the function is real and defined.

As the function has no undefined points nor domain constraints.

Thus, the domain is

$-\infty \:$

Therefore, we conclude that

$\mathrm{Domain\:of\:}\:x+3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

The graph is also attached.

Given a set of data that is skewed-left, there is at least _____ % of the data within 2 standard deviations.

Rasek [7]

Answer:

Step-by-step explanation:

For non-normal distributions, we use Chebyshev's Theorem.

Chebyshev Theorem

The Chebyshev Theorem states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

An in general terms, the percentage of measures within k standard deviations of the mean is given by $100(1 - \frac{1}{k^{2}})$ .

In this question:

Within 2 standard deviations of the mean, so 75%.

Solve (x² - 16)(x² - 9) = 0

Karo-lina-s [1.5K]

Answer:

x=-4,4,-3,3

Step-by-step explanation:

Factor by the difference of two squares

${x}^{2} - {y}^{2} = (x + y)(x - y)$

${x}^{2} - 16 = (x + 4)(x - 4) \\ {x}^{2} - 9 = (x + 3)( x - 3)$

$(x + 4)(x - 4)(x + 3)(x - 3) = 0$

Therefore, our answer is x = -4,4,-3,3
