Question

If anyone is onlie can they help me????

Answer 1

yees?

Answer 2

Which of the following does not represent a function?

graph of positive parabola oriented about the y axis with y intercept at negative 6
graph of a line with negative slope through the origin
graph of an absolute value function
graph of a parabola symmetric about the x axis with x intercept at negative 5

Answer 3

D,

Answer 4

this is not y as a function of x, but rather x as a funciton of y

Answer 5

for example, it could be x=y^2-5

Question 23 (Multiple Choice Worth 1 points)

(03.01 MC)

The tables below show the values of y corresponding to different values of x:


Table A
x 3 2 1
y 1 0 0
Table B
x 3 5 5
y −2 1 2


Which statement is true for the tables?
Both Table A and Table B represent functions.
Both Table A and Table B do not represent functions.
Table A does not represent a function, but Table B represents a function.
Table A represents a function, but Table B does not represent a function.

Answer 7

if you solve for y, you get y= plus/minus sqrt(x+5),

Answer 8

Can you help me with the other one???

Answer 9

D again

Answer 10

look for same x, different y

Answer 11

this is when you dont have a function

Answer 12

Question 21 (Multiple Choice Worth 1 points)

(03.05 MC)

The graph below shows the velocity f(t) of a runner during a certain time interval:

graph of line segment going through ordered pairs 0, 2 and 6, 8. Graph of another line segment through ordered pairs 6, 8 and 8, 0. Label on the x axis is time in seconds and label on the y axis is velocity in meters per second

Which of the following describes the intercepts on the graph?

The initial velocity of the runner was 8 m/s, and the runner stopped after 2 seconds.
The initial velocity of the runner was 2 m/s, and the runner stopped after 8 seconds.
The initial acceleration of the runner was 8 m/s2, and the runner stopped after 2 seconds.
The initial acceleration of the runner was 2 m/s2, and the runner stopped after 8 seconds.

Answer 13

Can u help me again????

Answer 14

at 8 sec , v=0

Answer 15

Are you guessing????

Answer 16

no, I am sovling

Answer 17

I mean B

Answer 18

sorry, brain farted

Answer 19

initial accerlation is 1 not 2

Answer 20

initial velocity is 2, becuase x=0 and v=2
