Answer 1

@Vocaloid

Answer 2

for a (the thing with the blue ovals) your domain would just be all the x-values and all the y-values since all of them are included with the arrows

Answer 3

A. the second part

B. the third part

Answer 4

i figured it out

Answer 5

yeah those answers are right, gj

Answer 6

ok

Answer 7

Answer 8

do the vertical line test

if you can draw a vertical line that crosses more than 2 points on the graph, then it is not a function

Answer 9

let me know what you get for each graph

Answer 10

1. Not a function

2. function

3. non a function

4. function

Answer 11

am i correct ?

Answer 12

awesome, that's it

Answer 13

really ?

Answer 14

don't worry about it

Answer 19

The function f(x) is graphed on the coordinate plane.

What is f(−4) ?



Enter your answer in the box.

f(−4) = __________

Answer 20

put your finger on x = -4

go straight up until you touch the graph

then go straight to the right until you touch the y-axis

what y-value do you get?

Answer 21

8

Answer 22

4

Answer 23

good, 4

Answer 24

so 4 is your answer

Answer 25

The graph shows the profit, y, of a community fundraiser, with respect to the number of tickets sold, x.

Use the graph to complete each statement.

Drag and drop the answers into the boxes.

The y-intercept is ___________ .

The y-intercept represents ___________

20, 35, the profit per ticket, the initial amount of expenses, the number of tickets sold, or -700

Answer 26

Answer 27

i forgot

Answer 28

hint: the y-intercept is the value of y when x = 0

Answer 29

when x = 0, what is the value of the graph?

Answer 30

x value

Answer 31

what is y equal when x equals 0?

Answer 32

-700

Answer 33

i was trying to say 0 but i thought wrong

Answer 34

good, -700

Answer 35

but the computer wasn't acting right

Answer 36

if x = 0 that means no tickets were sold, so these must be the initial costs

Answer 37

that's it for your problem

Answer 38

so the y-intercept is the initial ampount

Answer 39

yes, they're the initial expenses

Answer 40

the y-intercept represents ?

Answer 41

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Vocaloid
yes, they're the initial expenses
\(\color{#0cbb34}{\text{End of Quote}}\)

Answer 42

no i meant by

look back at the question

Answer 43

I am.

Answer 44

I have stated the y-intercept represents the initial expenses.

Answer 45

but it's one

Answer 46

just pick one

Answer 47

you can't have both

Answer 48

on each question

Answer 49

here are your answer choices:

20, 35, the profit per ticket, the initial amount of expenses, the number of tickets sold, or -700

we have stated the y-intercept is -700 and this represents the initial expenses.

Answer 50

pick the two answer choices that match what I said.

Answer 51

oh i see

Answer 52

Graph f(x)=|x−2|+3 .

Answer 53

start with f(x) = |x| and apply the appropriate transformations

Answer 54

that;s what i did

Answer 55

^ start with this graph f(x) = |x|

then we translate 2 units to the right and 3 units up

Answer 56

the one that i did was right or wrong ?

Answer 57

the one you did was not correct

Answer 58

please see what I have written

Answer 59

your graph should look like a V

Answer 60

is this correct ?

Answer 61

please see what I have drawn

Answer 62

like that one ?

Answer 63

yes

Answer 64

i kinda like can't do it on mine

Answer 65

draw a point at (2,3) and make a V-shaped graph

Answer 66

the slope on the right-side should be 1 and the slope on the left-side should be -1

Answer 67

like this ?

Answer 68

yupp good

Answer 69

or like this

Answer 70

which one ?

Answer 71

uh they both look the same to me but the first one i guess?

Answer 72

you think ?

Answer 73

first one is correct

Answer 74

ok last one

Answer 75

Graph the function f(x)=−1/4x−2.

Answer 76

start with the point (0,-2)

Answer 77

this correct ?

Answer 78

hint: try finding the x-intercept by setting f(x) = 0

Answer 79

if 0 = (−1/4)x−2 then x = ?

Answer 80

-8

Answer 81

awesome job! so your graph should connect (-8,0) and (0,-2) which means you need to adjust your original graph

Answer 82

is this it ?

Answer 83

yupp good

can we close this an open a new question please ^^"

Answer 84

yes ma'am
