Question

I have to graph this polynomial
f(x)=x^3-4x+1
Where do I start?

Answer 1

Do you know what x^3 looks like?

Answer 2

yes, like if I put in a 1, x is still 1. If I put in a 2, x is 8

Answer 3

Let's start with x=0

Answer 4

\[f(0)=0^3 - 4*0 + 1 = 1\]

Answer 5

You're having to actually graph this, right?

Answer 6

Yes

Answer 7

Do you know to what x-values are you having to graph it?

Answer 8

So, with x=0, y just =-3, right?

Answer 9

With x=0, y=1

Answer 10

because zero cubed is zero and four times zero is still zero.

Answer 11

Oh my goodness :/ I was adding it and driving myself nuts, I'm good, thanks:)

Answer 12

I've been doing toooo much homework sorry

Answer 13

You're fine lol

Answer 14

You still need help with this one?

Answer 15

No, I can get my five points now and make my graph. Thanks.

Answer 16

(0, 1) (1,3)(-1,4)(2,1)(-2,1)?

no

Answer 17

For x = 1
1^3 - 4*1 + 1 = 1 - 4 + 1 = -2

Answer 18

(0, 1)
(1, -2)

Answer 19

Thanks

Answer 20

Yup
