Answer: 1.45 is a growth factor.
Explanation:
Exponential growth function:
, where A = initial value , b = growth factor (if b>1)
Here, The expression
models the number of billions of genetic sequence bases available in the public database of the Whole Genome Shotgun project t years since 2002.
Here, b=1.45 >1
Thus,1.45 is a growth factor.
