Given:
The exponential function is,
Required:
The growth factor in the exponential function.
Step-by-step explanation:
The growth function is given by,
where, a is initial amount , a>0, t is time and r is rate of increase, r>0.
Hence, growth factor in the exponential function is given by, 1.25.
Final Answer:
Growth factor in the exponential function is 1.25.
