Given:
The exponential function is,
[tex]y=45000\left(1.25\right)^5[/tex]Required:
The growth factor in the exponential function.
Explanation:
The growth function is given by,
[tex]f(t)=a\left(1+r\right)^t[/tex]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.
