Step-by-step explanation:
Question b has already been answered in part one. This is an exponential function.
C) 7 is the initial number of people who received the email;
7*2^n is the number of people who receive the email on day n;
2 is the factor of which the number of people increases each day.
D) On day 5,
[tex] {2}^{5} \times 7 = 32 \times 7 =224[/tex]
people will have received the email.
E) 2; 0 (no people has received the email on day 0). The equation is
[tex]y = {2}^{x} \times 7[/tex]
With x in the natural numbers
