Question

Consider the following function.

Answer 1

Consider the following function.

\[k(x) = -2x^{5}\]

Find two points on the graph of this function, other than the origin, that fit within the given [−10,10] by [−10,10] grid. Express each coordinate as an integer or simplified fraction, or round to four decimal places as necessary.

Answer 2

Enter the coordinates to plot points on the graph.

A: ( , )

B: ( , )

Answer 3

@tranquility

Answer 4

If you type the function into desmos....
then find which coordinate points fit in the [-10,10] and [-10,10] grid

Answer 5

Answer 6

Just pick a number and replace it with x and solve.

Answer 7

4

Answer 8

-4x^5

Answer 9

It's not rocket science

Answer 10

Pick a number

Plug it in

SImplify it

Answer 11

okay i just want to make sure i have the right number based from your judgement , that's all

Answer 12

That was not right at all

Answer 13

You just have to choose any number between -10 and 10 and as long as it gives you a y-value that's between -10 and 10, you can plot it on your graph.

I would suggest choosing small numbers like -2, -1, 1, or 2

Answer 14

okay , -1

Answer 15

now

Answer 16

plug it in...

-2x^5

replace x with -1

and simplify.....

Answer 17

-1x^5

Answer 18

-x^5

Answer 19

not at all

Answer 20

replace x with -1

it's simple

-2 * (-1)^5

How difficult is that?

Answer 21

i'm sorry i'm not good at math at first to put it together , my apologizes

Answer 22

2

Answer 23

Good. Now this number that you just got

it is


the


y-value.


The number you plugged in... which was -1...

is the

x-value


okay?


How do you write an ordered pair?

(x, y)

x value first
y value second

what did we say the x-value was?
-1

what is the y-value of the point on the graph at x = -1

it's 2


so how do you write the point?

(-1, 2)

Do you get it?

Answer 24

All you have to do now is pick another number for x and solve it

Answer 25

i see, i get it so far

Answer 26

-2

Answer 27

-2 * (-2)^5

am i right

Answer 28

simplify it now

Answer 29

actually -2 wouldn't work because you'll be getting a number larger than 10

so you probably should just use 1

Answer 30

Because your question states that it needs to fit on the -10 to 10 grid

with x = -2, you get y = 64

and 64 is waaaay above 10

so -2 would not work for an answer

Answer 31

-2 * (1)^5

Answer 32

And simplify it

Answer 33

-2

Answer 34

How would you write the point for that?

Answer 35

-2, 2

Answer 36

No. You plugged in 1.

1 is the x-coordinate.
-2 is the y-coordinate

Answer 37

this is the x-axis

Answer 38

this is the y-axis

Answer 39

Alright

Answer 40

You need to really brush up on basics.

Answer 41

oh i get a little bit now

Answer 42

(1, -2)

Answer 43

Yes

so your final answer is

(-1, 2) and (1, -2)

Answer 44

okay thank you tran
