What is the growth factor of fx123x12 What is the growth fac

Solution

The expression is not clear. Either f(x) = -1/2(3^x+1) -2 or, f(x) = -1/2(3^x +1) -2.

In the former case, f(x) = -3/2(3^x ) -2 and in the latter case, f(x) = -1/2(3^x ) -5/2.

We know that when f(x) = ab^x , the growth/decay factor is b. Here, b = 3 in both the above eventualities. Therefore, the growth factor is 3.
