Question

What is the graph of the function rule?

y = |4x| + 3

Answer 1

You could make a table of values if you're clueless on how to graph it.

Or, graph it using transformations of |x|.

Answer 2

it's a peace sign. LOL v(^^)v

Answer 3

Well I know I have to subtract 3, so I can get 4x by itself. But what else do I subtract by 3 if we don't know what y is?

Answer 6

I think the function rules is when the variables are related, you can make a table

Answer 7

I think you should make a table an replace it with r x values. Ex: -2 and plug that in and solve

Answer 8

x value's *

Answer 10

f(x) is a fancy way of saying y. For example here:

Can't give you the answer I already got a warning today for no reason..

Answer 12

"Well I know I have to subtract 3, so I can get 4x by itself. But what else do I subtract by 3 if we don't know what y is?"

Do not do this, you aren't solving for x.

Make a table of x and y values.

Answer 14

Make a table, plot the point and draw the line, simple :)

Answer 15

Are you sure it's that one? Describe why you think it's that one.

Answer 16

Well because it adds three... And it seems to start as a positive. Ugh I'm so bad at this.

Answer 17

If it's 4x + 3

It can be like

4(1) + 3 = 7
4(2) + 3 = 11
4(3) + 3 = 15

Is it like this..?

Answer 18

I'd include a negative, -2 -1 0 1 2

Answer 19

4(-2) + 3 = -5
4(-1) + 3 = -1
4(0) + 3 = 3
4(1) + 3 = 7
4(2) + 3 = 11

Like this?

Answer 20

You ignored the absolute value sign.

Answer 21

Oh true. So that would make the -2 and the -1, positive 2 and 1, right?

Answer 22

Yesh

Answer 23

Because it would be |4(-2)| and that would equal |-8| and that would actually be 8? And then add the 3, of course.

Answer 24

Yes.

Answer 25

Did that answer you're question? :)

Answer 26

Yes but I don't understand how I'd graph that.

Answer 27

Plot the points? and draw the line

Answer 28

That's the point of a table of values. You write out the table of x and y, so you can plot the points.

Answer 29

Just to make sure... |4(-2)| + 3 = 11.... That would be (-2, 11), right..? If x, in the problem, was -2.

Answer 30

Yes, that's why you should write a table to avoid any confusion.

Answer 31

Yup

Answer 32

Okay, yeah, now I understand it.
