Answer 1

@Angle

Answer 2

first graph: crosses the x-axis 3 times
second graph: crosses the x-axis 6 times
third graph: crosses the x-axis 2 times

Answer 3

okay, that means?

Answer 4

is 3 odd or even?

Answer 5

oh.

Answer 6

...

Answer 7

odd

Answer 8

so the other two are even

Answer 9

aye aye
I'm assuming you get the idea? x'D

Answer 10

although

Answer 11

I might have made a mistake with the second one
I think they mean that it keeps going up and down forever
which would mean that it is not odd nor even
because it crosses the x-axis infinitely many times

Answer 12

ok

Answer 13

what's your guess?

Answer 14

C

Answer 15

D?

Answer 16

yup

Answer 17

that's the other graph they're talking about

Answer 18

alright

Answer 19

let's consider each option

A: they want to look at the rates of each graph between x=-5 and x=-3
for f(x) the change is about 1
for g(x) the change is about 2
does "f(x) increase faster than g(x)"?

B: they want to see if the graph is negative on the left side
for f(x), x=-1 is about 8 which is positive
for g(x), x=-1 is about 13 which is also positive
are "f(x) and g(x) negative when x is less than 0"?

Answer 20

C: they want us to look at the y intercepts
f(x), the y intercept is 15
g(x), the y intercept is 20
does "g(x) have a greater y intercept than f(x)"?

D: are both graphs increasing?

Answer 21

for D, obviously yes

Answer 22

mhm :) yup

Answer 23

for C, is the graph you made G(x)?

Answer 24

yes

Answer 25

then C too

Answer 26

awesome ^_^

Answer 27

that it?

Answer 28

yes ^_^

Answer 29

for this, we just use the slope formula

\(slope = \large \frac{y_2 - y_1}{x_2 - x_1}\)

Answer 30

so the first interval = \(\large \frac{5760 - 1920}{9-7}\)

and the second interval = \(\large \frac{945-105}{6-4}\)

Answer 31

what do you get for each?

Answer 32

uh...

Answer 33

wait do i divide?

Answer 34

subtract first
then divide

Answer 35

1741 for the first one

Answer 36

and 420 for the other

Answer 37

then the question is "how much greater" ?

Answer 38

wait... try the first one again?

Answer 39

I got 1920 for the first one

Answer 40

then 1920 - 420 = ?

Answer 41

1500

Answer 42

tah dahhh

Answer 43

maintainence starting soon
ask a new question when we get back

Answer 44

back

Answer 45

ask a new question for your question?
I gtg

Answer 46

@princeevee

for your most recent unanswered question:

(f+g)(x) = f(x) + g(x)

you have been given that
f(x) = 8x^2 + 16x + 6
and
g(x) = x^3 - 3x^2 - 9

so
f(x) + g(x) = (8x^2 + 16x + 6) + (x^3 - 3x^2 - 9)


we then add like terms:
= x^3 + (8x^2 - 3x^2) + 16x + (6 - 9)

you should be able to get the answer from there, if you get stuck, still need help, or would like for us to check your answer, feel free to tag me or Angle

Good luck! :-)
