Question

Solved with the help of two very patient people.

Answer 1

no you graph all of it the x and the y's must be graphed

Answer 2

domain would be written [0, 4] (zero to four inclusive)
range would be written [1, 5] (1 to 5 inclusive)

ordered pairs are your (x, y) pairs which are (input, output)

so you have (0, 1), (1, 2), (2, 3), (4, 5)

you graph the ordered pairs (x,y)

Answer 3

no graph the order pairs above for ex:0,1

Answer 4

yes

Answer 5

i'm sorry

Answer 6

so it would be 2x+4 the x is a exponent so you would substitute the value that you multply then add to get the y values i'm sorry i don't know how else to explain i'm just a freshman in high school

Answer 7

your welcome

Answer 8

Looks good to me.

Answer 9

You can figure out the function. Every time x increases by 1, y also increases by 1.
(in the last pair, x and y both increase by 2)
So it is a straight line. Slope = rise / run = 1 / 1 = 1
So it is a 45 degree line. when x = 0, y = 1. That will be your y-intercept.

The function is y = mx + b where m is slope and b is the y-intercept.

You can substitute for m and b and figure out the function.

Answer 10

Just plot the 4 points and join them all using a ruler.

If they ask for for the function you can use the method in my previous reply.

Answer 11

@get002

I do not agree with this:

>>or domain I have [0,4] for range i have [1,5]

As I understand the question, the domain is discrete and consists of four elements. The same for the range.

This notation --> [0,4] means all real numbers from zero to four, including 0 and 4. There are infinitely many of those. That is not what you are given as the domain.

For domain, I would say {0,1,2,4} just as you wrote.
For range, I would say {1,2,3,5} just as you wrote.

I agree with this: corresponding ordered pairs i have (0,1), (1,2), (2,3), (4,5)

And, to my thinking, the graph consists of exactly those four points.
Do not connect them.

Answer 12

What Directrix said above makes sense and may be the right thing to do.

Answer 13

@getoo2 The question does not ask for a rule.

Answer 14

I agree with @Directrix about domain and range logic.

but if we graph it and connect the dots, aren't there infinitely many x and y between the given integers?

Answer 15

@Euler271 We are not connecting the dots. At least, I am not because this function consists of exactly 4 ordered pairs.

Answer 16

ok then, I agree 100%

Answer 17

No connecting the dots. We made the tacit assumption the function was continuous. But it was not suggested in the problem.

Answer 18

@getoo2 Post your graph so that we can see what you are doing.

Do this and you will be finished:
graph the function with the domain given.

Plot the four points and you are finished. Do not join them.

Answer 19

Attached is a virtual sheet of graphing paper.

Answer 20

No problem with that. We just need to see your graph.

You can also click on the blue DRAW tab below and sketch the graph there.

Answer 21

You have just plotted the x values.

You should plot the 4 (x,y) pairs.

Answer 22

You plotted these ordered pairs: (0,0); (1,0); (2,0); (4,0)

That is not what we are doing.

We are plotting these ordered pairs: (0,1), (1,2), (2,3), (4,5)
