they are squared...

Answer 10

left four

Answer 11

i though it was a but it said i was wrong

Answer 12

than your grading system is wrong, or you wrote the equation wrong. I put those into desmos, its not wrong

Answer 13

i have another one i need help with... do you think you can help?

Answer 14

ya, np

Answer 15

Functions 1 and 2 are shown below:

Function 1: f(x) = −4x2 + 6x + 3
A graph of a parabola with x intercepts negative 1, 0 and 1, 0 and a vertex of 0, 3 is shown.

Which function has a larger maximum? Type your answer as 1 or 2.

Answer 16

i said 1 but i got it wrong...

Answer 17

ill check it

Answer 18

what is function 2?

Answer 19

okay thanks

Answer 20

its a graph...

Answer 21

ok

Answer 23

this is the question...

Answer 24

#2 this is the exam i need help with

Answer 25

Was it number 2?

Answer 26

second time taking this...

Answer 27

number two is wider, therefore, the maximum is greater, yes, it is 2

Answer 28

ok thanks

Answer 29

np

Answer 30

now number 3 i said all real numbers and got it wrong...

Answer 31

Identify the domain of the graph of y = −x2 − 6x − 13.

Answer 32

All real numbers
x ≤ −4
x ≥ −6
x ≥ −2

Answer 33

thanks for helping me...

Answer 34

np

Answer 35

i suck at algebra

Answer 36

the domain is the extent of x, so when you graph it, you need to see where it stops, IF it stops

Answer 37

ok

Answer 38

thats odd

Answer 39

what?

Answer 40

its a parabola, the domain is infinite

Answer 41

okay...and that means what?

Answer 42

all real numbers should work

Answer 43

okay ill try it again

Answer 44

A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 48t where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent?

t = 1.5; it takes 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground
t = 1.5; it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground
t = 3; it takes 3 seconds to reach the maximum height and 3 seconds to fall back to the ground
t = 3; it takes 3 seconds to reach the maximum height and 6 seconds to fall back to the ground

Answer 45

ok this one i said a but got it wrong...

Answer 46

brewski, thats along question. just a minute

Answer 47

okay

Answer 48

the second one

Answer 49

okay thanks for checking my answers

Answer 50

Determine which of the following statements is true concerning the values described in column #1 and column #2.


Column #1 Column #2
The x-coordinate of the vertex of the graph of
y = −2x2 − 4x + 12 The x-coordinate of the vertex of the graph of
y = x2 − 4x + 3
The value found in column #1 is greater than the value found in column #2.
The value found in column #1 is less than the value found in column #2.
The value found in column #1 is equivalent to the value found in column #2.
The relationship between column #1 and column #2 cannot be determined by the information given.

Answer 51

i said b and got this one wrong

Answer 52

i think a but im not sure

Answer 53

okay...

Answer 54

The distance traveled, in feet, of a ball dropped from a tall building is modeled by the equation d(t) = 16t2 where d equals the distance traveled at time t seconds and t equals the time in seconds. What does the average rate of change of d(t) from t = 2 to t = 5 represent?

The ball travels an average distance of 112 feet from 2 seconds to 5 seconds.
The ball falls down with an average speed of 48 feet per second from 2 seconds to 5 seconds.
The ball falls down with an average speed of 112 feet per second from 2 seconds to 5 seconds.
The ball travels an average distance of 48 feet from 2 seconds to 5 seconds.

Answer 55

next one....one more after this...

Answer 56

D?

Answer 57

i think...

Answer 58

Choose the equation below whose axis of symmetry is x = 0.

y = x2 + 2x
y = x2 − 16x + 58
y = x2 + 2
y = x2 − 4x + 2

last one and i said this was a and got it wrong....
