A.1
B.8
C.32
D.224

2.What is the initial number of bacteria? (at time zero) *
A.0
B.1
C.4
D.32

3. Write a rule/ equation for this picture:
(2nd attachment)
A. y = 4 * 8^x
B. y = 4 + 8x
C. y = 4^x + 8
D. y = 4x + 8

4.Suppose you started with 100 bacteria, but they still grew by the same growth factor. Write the new function rule for this situation.

A. y = 4 + 8x
B. y = 100x + 8
C. y = 100
D. y = 100 * 8^x

Also, I'm home schooled and really need friends so if ur interested fell free 2 hmu :))
