What are the domain and range of the mathematical function f(x)=x-3

Mathematics

Domain: All Real Numbers

Range: All Real Numbers

Further explanation:

Let us define domain and range first

Domain is the set of all possible inputs for a function on which the function is defined.

While range is the output of the function obtained by inputting domain

Here,

Given function is:

f(x) =x-3

The function will not be undefined on any input, so the domain of the function is all real numbers.

Similarly, the range will also be all real numbers as there is no input which makes it undefined.

Keywords: Domain, range of a function

What is the domain and range of each relation?
LUCKY_DIMON [66]

Answer:

\text{Domain of}R_1=\{-2,0,2,4\}  and \text{Range of}R_1=\{-3,-1,0\}

\text{Domain of}R_2=\{-3,-1,0,3\}  and \text{Range of}R_2=\{-1,0,1,2,3\}

Step-by-step explanation:

Domain is the set of input values or x-values.

Range is the set of output values or y-values.

According to the relation mapping diagram, the relation is

R_1=\{(-2,-3),(-2,-1),(0,0),(2,0),(4,-3)\}

So,

\text{Domain of}R_1=\{-2,0,2,4\}

\text{Range of}R_1=\{-3,-1,0\}

In the graph 5 points are plotted. So, the relation is  

R_2=\{(-3,1),(-1,-1),(0,0),(3,2),(3,3)\}

So,

\text{Domain of}R_2=\{-3,-1,0,3\}

\text{Range of}R_2=\{-1,0,1,2,3\}

avanturin [10]

You're going to want to take the total, which is $353.00 and subtract the initial cost, which is $84.00, the number now should be $269. Using that total divide it by $68.00, there you should find your answer of about 4 hours. The precise answer is 3.99588235. But you would round that to 4 hours.

An Austrian study was completed to determine if untrained sea lions and sea lionesses could follow various experimenter-given cu
Sholpan [36]

Using the z-distribution, it is found that since the test statistic is greater than the critical value for the right-tailed test, this result shows that Zwerg can correctly follow this type of direction by an experimenter more than 50% of the time.

<h3>What are the hypothesis?</h3>
  • At the null hypothesis, it is tested if Zwerg cannot correctly follow this type of direction by an experimenter more than 50% of the time, that is:

H_0: p \leq 0.5

  • At the alternative hypothesis, it is tested if Zwerg can correctly follow this type of direction by an experimenter more than 50% of the time, that is:

H_1: p > 0.5

<h3>Test statistic</h3>

The <em>test statistic</em> is given by:

z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}

In which:

  • \overline{p} is the sample proportion.
  • p is the proportion tested at the null hypothesis.
  • n is the sample size.

For this problem, the parameters are:

n = 48, \overline{p} = \frac{37}{48} = 0.7708, p = 0.5

The value of the <em>test statistic</em> is:

z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}

z = \frac{0.7708 - 0.5}{\sqrt{\frac{0.5(0.5)}{48}}}

z = 3.75

Considering a <u>right-tailed test</u>, as we are testing if the proportion is greater than a value, with a <u>significance level of 0.05</u>, the critical value for the z-distribution is z^{\ast} = 1.645.

Since the test statistic is greater than the critical value for the right-tailed test, this result shows that Zwerg can correctly follow this type of direction by an experimenter more than 50% of the time.
