Question

Help graphing functions!

Answer 1

I don't know how to graph long functions on my ti-84. Can someone help. I will post the equation and function in a sec.

Answer 2

Here is the question, I need to know how to graph both things
f(x) = x3 + x2 − 2x + 1, what is the resulting function when f(x) is shifted to the left 1 unit?

Answer 3

I need to know how to graph on my calculator, I can't use a computer during school

Answer 4

well if you wanted to put in x^3 you would put the variable x ^ sign then 3

Answer 5

here is a good video

Answer 6

I just don't know how to get it into thee graph. I know variables and stuff. I can't get past the y= screen. I put the equation in y= screen, but I don't know what to do after that

Answer 7

@Malay_80 I posted a video this should help

Answer 8

ok, hang on. Ill check it out

Answer 9

Press "graph" on the right after the y= screen.

Answer 10

the video helped, now I need help on the question
Given the function f(x) = x^3 + x^2 − 2x + 1, what is the resulting function when f(x) is shifted to the left 1 unit?

Answer 11

For any function f(x) transformed to g(x), we have, in general,
g(x)=a*f(bx-h)+k
where
a=vertical stretch, a=1 if no change in scale/stretch.
b=horizontal stretch, b=1 if no change in scale/stretch.
h=shift to the right h units for h>0, and to the left for h<0. h=0 if no left/right shift.
k=shift up k units if k>0, and shift down if k<0. k=0 if no up/down shift.
