Question

For the function y = f(x), what is the ordered pair for the point on the graph when x = 3n - 4?

Answer 1

(3n - 4, f(n))
(3n - 4, f(3n - 4))
(x, f(3n))
(x, 3n - 4)

Answer 2

For a function y=f(x), when x=2, my ordered pair would be \((2,~f(2))\).
Do you agree with that?

Answer 3

And same thing is when x=3n-4, except that instead of a 2 I got \(\small3{\rm n}-4\).

Answer 4

mhm okay yea i understand

Answer 5

so its d right

Answer 6

no

Answer 7

let me ask you again.

I have a function y=f(x), and my x=4, what is the ordered pair?

Answer 8

\[(4,f4)\]

Answer 9

yes, \(\color{blue}{(4,f(4))}\)

Answer 10

Ok, now my function is still f(x), but my x=8b
what is my ordered pair then?

Answer 11

\[(8b, f(8b))\]?

Answer 12

yes, that is right

Answer 13

now, my function is still f(x), and my x=3n-4

my ordered pair is?

Answer 14

\[(3n-4 , f(3n-4))\]

Answer 15

yes, that is right....

Answer 16

so b is the answer

Answer 17

yes, B is the answer.

Answer 18

Awesome thank you so much again ! ;p

Answer 19

yw

Answer 20

could you help me with this one

Answer 21

The table below represents the velocity of a car as a function of time:


Time
(second)
x
Velocity
(m/s)
f (x)
15
45
22
66
29
87
36
108


The average rate of change of the function between x = 15 to x = 29 is __________m/s2 and represents the car's acceleration.

Answer 22

thats the table

Answer 23

I'm thinking the answer is 32 but im not so sure

Answer 24

ok, you have two points
(15,45) and (29,87)

all you need to do is to find the slope.
