How do you find the domain and range on a graph

Mathematics
1 answer:
egoroff_w [7]2 years ago
5 0

Look at the values on the axes of the graph.

Step-by-step explanation:

Domain can be found by looking at the x-axis of a graph. Range can be found by looking at the y-axis of a graph. You have to find at what point on the axis is the graph stopping.

For example, if I wanted the domain of y=x, I would say it is all real numbers. Why? Because when we look along the x-axis, from left to right, we can see that it continues going until infinity. That means that there are no stopping points in the graph of y=x.

PLEASE help with these math questions
SIZIF [17.4K]
Questions 1, 2, 3, and 4 are exercises to give you practice with
common denominators.  For each of these questions, change all
the fractions to common denominators, and the answers jump out at you.

#1).  5/12 = 25/60
         2/5  =  24/60
Make um negative, and then you'll have the answer right away.


#2).  The one that's negative is obviously the least.
Both positive ones must be bigger than the negative one.
For the positive ones:

           2/5  =  6/15
           2/3  =  10/15 .
Now it's easy.


#3).  This is tough.  The least common denominator is  2,520 !
It's probably easier to just do the divisions and get the decimals
for each fraction.

               -5/8  =  -0.625
               -7/9  =  -0.777...
               -4/5  =  -0.8
               -3/7  =  -0.428...
Now it's easy to line um up.


#4).  Sneaky one.
      Look closely at each fraction.
      B, C, and D are all less than 1, so they're not between 1 and anything more than 1.
      8/5 is the only one that's more than 1.     


#5).  A fraction is just a short way to write a division problem.
When you see a fraction, it means

               "the top number divided by the bottom number" .

When you actually do the division, the quotient you get
is the decimal form of the fraction.

To change a decimal into a percent,
move the decimal point two places that way  ==> .

The numbers in the boxes at the bottom of #5 are the correct numbers,
but they both should be negative.  (because the -3/8 is negative)

You finish washing 3/4 of your windows in an hour and a half. At that rate, how much longer will it take you to finish washing a
Marysya12 [62]
It takes you 90 minutes to wash 3/4 of your windows

Multiply both numbers by 4.

It takes you 360 minutes to wash 3 of your windows.

Divide both numbers by 3.

It takes you 120 minutes to wash 1 of your windows.

120 minutes = 2 hours.

It will take you 2 hours to wash all the windows.

PLEASE HELP(will mark brainiest) Draw a quadrilateral A'B'C'D' that is a translation (x + 2, y - 4) of quadrilateral ABCD.
yuradex [85]

Answer:

New coordinates:

A: (2,-4)

B: (6,-4)

C: (7,1)

D: (3,1)

Step-by-step explanation:

You translate each of the starting coordinates by adding or subtracting them by the coordinates given.  

x coordinates:  0+2=2              y coordinates:   0-4= -4

                         4+2=6                                         0-4= -4

                         5+2=7                                          5-4= 1

                         1+2=3                                           5-4= 1

The pair of points is on the graph of an inverse variation. Find the missing value. (1.6, 6) and (8, y) 0.03 30 1.2 0.83
ZanzabumX [31]
One may note that (1.6 , 6)  is just another way to say x = 1.6 when y = 6.

and that (8 , y) is another way to say x = 8 and y is who knows.

\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad  y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad  variation
\end{array}\\\\
-------------------------------

\bf \textit{we know that }
\begin{cases}
x=1.6\\
y=6
\end{cases}\implies 6=\cfrac{k}{1.6}\implies 6(1.6)=k\implies 9.6=k
\\\\\\
\qquad therefore\qquad \boxed{y=\cfrac{9.6}{x}}
\\\\\\
\textit{when x = 8, what is \underline{y}?}\qquad y=\cfrac{9.6}{8}
