Harrison shared his video with 5 friends. His friends continued to share it, doubling the number of viewers each day.
f(x) = 5(2)x

Anita shared her photo with 42 followers. Each of them shared it with 2 friends, doubling the number of viewers each day
Day Viewers
0 42
1 84
2 168

Juan shared his post with 3 friends, who each shared it with 3 more friends. They continued sharing at the same rate


Krista shared her photo with 8 friends, who each shared it with 3 friends. This pattern continued. f(x) = 8(3)x



1.State which two students you are studying so your instructor knows for whom each partner is responsible.
2.Provide an exponential function representing Anita's social media shares.
3.Provide an exponential function representing Juan's social media shares.
4.Using the functions for each student, predict how many shares each student's post will have received on Day 3 and then on Day 10. Justify your answers.
5.Based on your results, which student's post travels the fastest? How is this shown in the equation form of the functions?
6.If you had to choose, would you prefer a post with fewer friends initially but more shares or more friends initially but fewer shares? Does your partner agree or disagree? Can you think of reasons why more or fewer shares are preferable? Justify your answer with your calculations from previous questions.

2. Anita:   f(x) = 42(2)^x
3. Juan: f(x) = 3^x
4. 
Harrison : f(x) = 5(2)^x   → f(3) = 5(2)³ = 5(8) = 40 ; f(10) = 5(2)^10 = 5(1,024) = 5,120
Anita : f(x) = 42(2)^x → f(3) = 42(2)³ = 42(8) = 336 ; f(10) = 42(2)^10 = 42(1,024) = 43,008
Juan : f(x) = 3^x → f(3) = 3^3 = 27 ; f(10) = 3^10 = 59,049
Krista : f(x) = 8(3)^x → f(3) = 8(3)^3 = 8(27) = 216 ; f(10) = 8(3)^10 = 8(59,049) = 472,392

5. Krista's post travels the fastest. It reached 472,392 in 10 days.
6. Fewer friends initially but more shares.

Answer:

1. Anita:   f(x) = 42(2)^x

2. Juan: f(x) = 3^x

3.

Harrison : f(x) = 5(2)^x   → f(3) = 5(2)³ = 5(8) = 40 ; f(10) = 5(2)^10 = 5(1,024) = 5,120

Anita : f(x) = 42(2)^x → f(3) = 42(2)³ = 42(8) = 336 ; f(10) = 42(2)^10 = 42(1,024) = 43,008

Juan : f(x) = 3^x → f(3) = 3^3 = 27 ; f(10) = 3^10 = 59,049

Krista : f(x) = 8(3)^x → f(3) = 8(3)^3 = 8(27) = 216 ; f(10) = 8(3)^10 = 8(59,049) = 472,392

4. Krista's post travels the fastest. in 10 days they reached 472,392s.

5. more shares but fewer friends initially
