Three Algebra 1 students are comparing how fast their social media posts have spread. Their results are shown in the following table. Description Amber shared her photo with 3 people. They continued to share it, so the number of shares increases every day as shown by the function. Ben shared his post with 2 friends. Each of those friends shares with 3 more every day, so the number of shares triples every day. Carter shared his post with 10 friends, who each share with only 2 people each day. Social Media Post Shares f(x) = 3(4)x Day Number of Shares 0 2 1 6 2 18 Carter shared his post with 10 friends, who each share with only 2 people each day.

hey @phi

3. anonymous

can ya'll help me please I really really need it.

4. anonymous

i relly dont know how to solve this problem thats why im trying to get help

5. anonymous

oh sorry for not putting the question I need help on, hold on please.

3.Graph each function using at least 3 points for each line. All graphs should be placed together on the same coordinate plane, so be sure to label each line

8. anonymous

if you need me to post the ones I already did to help out I will.

can you help me?

12. raiders88

nope sorry mate

13. raiders88

but here

14. anonymous

thank you.

@phi do you need me to post the others?

17. phi

what is the first question?

18. anonymous

1.Write an exponential function to represent the spread of Ben's social media post. Ben, f(x)=2*(3)x.

19. anonymous

I just need help on #3

20. phi

you mean this: Graph each function using at least 3 points for each line. All graphs should be placed together on the same coordinate plane, so be sure to label each line ?

21. anonymous

22. phi

one of the functions is given by a table, right ?

23. anonymous

I think so.

24. phi

it is hard to read the post. what are the 3 equations for A , B and C ? (I'm using their first initial, easier to type)

25. anonymous

A, f(x)=3*(4)^x B, f(x)=2*(3)x C, f(x)=10*(2)^x

26. phi

is B f(x)=2*3^x ?

27. anonymous

no.

28. anonymous

@phi

29. phi

you don't mean B is f(x)= 2*3*x = 6x ? I assume you mean $f(x) = 2 \cdot 3^x$ ?

30. anonymous

its not an exponential function, my teacher would have told me to correct that if it was.

31. phi

ok, so B is f(x)= 6x

32. phi

to plot we need points pick x=0, 1,2 and find f(x) if we have f(x)= 6x what is f(0) ? f(1) ? f(2) ?

33. anonymous

idk.

34. anonymous

how would I make the points from this?

35. anonymous
36. phi

ok. But first, ***Ben shared his post with 2 friends. Each of those friends shares with 3 more every day, so the number of shares triples every day. *** that says the first day 2 people have his post the next , 2*3 = 6 the next, 6*3 = 18 if we make that into an equation , it is $f(x) = 2 \cdot 3^x$ and we start at x=0 I am saying that equation for B must be exponential

37. anonymous

idk, my teacher didn't say anything about it and I don't want him coming back on more if I change it and its wrong you know?

38. anonymous

what are the 3 points for each line?

39. phi

let's do the first equation f(x)=3*(4)^x for x=0, 1, 2 when x is 0 you have 3* 4^0 4^0 is 1 (anything to the zero power is 1) so we have 3*1 = 3 and one point is (0,3) can you find the "y value" when x is 1 ?

40. phi

you have 3*(4)^x erase the x and write in 1 in its place 3*(4)^1 now do order of operations: exponents first. what is 4^1 ?

41. anonymous

4

42. anonymous

@peachpi

43. phi

ok, so you now have 3*4 = 12 so far we have (0,3) (1,12) what do you get for x=2 ?

44. anonymous

9

45. phi

you have 3*(4)^x erase the x and write in 2 in its place

46. phi

just do this: erase the x and write in 2 in its place what do you have ?

47. anonymous

you have 9

48. anonymous

3^2=9

49. phi

yes 3*3 is 9 but the formula for A is 3*4^x that is different from 3^x so far we found (0,3), (1,12), and now we want (2, ??) to find the number we erase the x and put in 2 in $3 \cdot 4^x$ can you erase the x and write in 2 instead ?

50. anonymous

sorry wrong way 4^2=16

51. phi

ok, but do the entire formula 3* 4^2 = what ?

52. anonymous

I looked at it wrong.

53. anonymous

48

54. phi

ok, so the 3rd point is (2,48) (0,3), (1,12), (2,48) time to plot these. do you know how to plot (0,3) ?

55. phi

do you use paper or a computer to plot points ?

56. anonymous

computer.

57. anonymous

how would I do it the easy way on computer?

58. phi

they want you to plot at least 3 points, so you have to find 3 points for each equation but assuming you show that work, it sounds ok to use a computer to plot the graphs. I use Geogebra (free download... but it takes a while) I know there are plotting tools on the web.

59. anonymous

what are the rest of the plots, im not trying to cheat or anthing but I will be in sireous trouble if I don't get a passing grade on this and I need it done now. please just tell me the other parts

60. phi

for example https://www.plotgraphs.com/ here is what it looks like
