Question

Someone please help me i dont understand

The tables below show the values of f(x) and g(x) for different values of x:

f(x) = 2(3)x

x f(x)
-2 0.22
-1 0.67
0 2
1 6
2 18


g(x) = 3x + 3
x g(x)
-2 3.11
-1 3.33
0 4
1 6
2 12


Based on the tables, what is the solution to the equation 2(3)x = 3x + 3?

Answer 1

@DarkBlueChocobo can you help?

Answer 2

The question is basically asking at what value of x do you see that g(x)=f(x). So look at both tables. When do you see that f(x) has the same value of x as g(x) does?

Answer 3

1?

Answer 4

1?

Answer 5

That's correct, so your answer is at x=1 :)

Answer 6

Thank you!

Answer 7

can you help me with one more?

Answer 8

Sure.

Answer 9

The graph below shows the velocity f(t) of a runner during a certain time interval:
Which of the following describes the intercepts on the graph?

A.The initial acceleration of the runner was 8 m/s2, and the runner stopped after 6 seconds.
B.The initial acceleration of the runner was 6 m/s2, and the runner stopped after 8 seconds.
C.The initial velocity of the runner was 8 m/s, and the runner stopped after 6 seconds.
D.The initial velocity of the runner was 6 m/s, and the runner stopped after 8 seconds.

Answer 10

When the time is t = 0, what is the velocity?

Answer 11

6?

Answer 12

At t=0 , what is the runner's velocity?

Answer 13

Correct, now when did the runner stop running, that is ... when does the runner have a speed of 0 ?

Answer 14

8?

Answer 15

Good, now what are the units of velocity?

Answer 16

seconds

Answer 17

No, look at your graph.

Answer 18

m/s and seconds

Answer 19

Yes, now match what you found with the correct choice. What do you get?

Answer 20

D

Answer 21

Good job :)

Answer 22

omg thank you!

Answer 23
