Question

1. Graph the function f(x) = –x3 + 1 by hand (not to be submitted).

Part 1: Use complete sentences to explain the process of graphing f(x) = –x3 + 1.
Part 2: What is the end behavior of f(x) = –x3 + 1?


2. The binomial x + 2 is the divisor of 4x3 – 9x2 – 30x + 8. Use complete sentences to explain how you use (either) polynomial division or synthetic division to find the quotient. Be sure to provide this quotient in your answer.

Answer 1

how far did you get

Answer 2

no where. this topic hasnt been my strong suit. i keep messing up

Answer 3

so ive kinda stop trying for most

Answer 4

to graph any function, you just need to graph a bunch of points

Answer 5

the more points you graph, the more accurate your graph will be

Answer 6

to get any point, you plug in a value of x to get a corresponding value of y

ex: plug in x = 0 into y = -x^3 + 1 to get y = 1 ----> the point (0,1) is on the graph

Answer 7

get enough points and you'll have the basic shape/form of the graph down

Answer 8

i used an online graphing calculator for this even tho she wants it by hand but is this what it should look like?

Answer 9

its says "(not to be submitted). ", so who cares how you get the graph really

Answer 10

but yes that looks right

Answer 11

so what's the end behavior?

Answer 12

left side continues going up and right side continues going up y-intercept is 1

Answer 13

right?

Answer 14

left is up, but right is down (look at the graph)

Answer 15

thats what i said.

Answer 16

no you said "right side continues going up"

Answer 17

oh well i meant down :/

Answer 18

ah ok

Answer 19

so that's the end behavior
