Byron bought some bananas at the store and noticed some fruit flies after returning home. The number of fruit flies can be modeled by the equation f(t)=8(2)t where f is the number of fruit flies after t days. Which graph models the number of fruit flies over the first 6 days?(2 points) Responses Skip to navigation

To model the number of fruit flies using the equation \( f(t) = 8 \cdot (2)^t \), we can calculate the number of fruit flies for \( t = 0 \) to \( t = 6 \):

  • At t = 0:
    \( f(0) = 8 \cdot (2)^0 = 8 \cdot 1 = 8 \)

  • At t = 1:
    \( f(1) = 8 \cdot (2)^1 = 8 \cdot 2 = 16 \)

  • At t = 2:
    \( f(2) = 8 \cdot (2)^2 = 8 \cdot 4 = 32 \)

  • At t = 3:
    \( f(3) = 8 \cdot (2)^3 = 8 \cdot 8 = 64 \)

  • At t = 4:
    \( f(4) = 8 \cdot (2)^4 = 8 \cdot 16 = 128 \)

  • At t = 5:
    \( f(5) = 8 \cdot (2)^5 = 8 \cdot 32 = 256 \)

  • At t = 6:
    \( f(6) = 8 \cdot (2)^6 = 8 \cdot 64 = 512 \)

Now, we can summarize the values:

  • Day 0: 8
  • Day 1: 16
  • Day 2: 32
  • Day 3: 64
  • Day 4: 128
  • Day 5: 256
  • Day 6: 512

With this exponential growth (doubling each day), the graph will show a steep upward curve starting at 8 and rapidly increasing to 512 over the 6 days.

Since I don't have the actual graphs to look at, you should look for a graph that:

  • Starts at around 8 on Day 0
  • Doubles each day and reaches approximately 512 by Day 6
  • Exhibits an exponential growth pattern, curving upwards steeply as t increases.

Choose the graph that matches this description!
