Explain why the initial value of any function of the form<br> f(x) = a(bx) is equal to a.
Serggg [28]

Answer:

Step-by-step explanation:

f(x) = a(b^x), the initial value is always a, because a is independent of x , so when x changes only b^x changes.ex if  a = 2, b = 3, and x = 0: f(0) = 2 (3^0) = 2  If x = 1, then f(1) = 2 (3^1) = 2 (3). If x = 2, then f(2) = 2 (3^2) = 2 (9), as you can see a still the same.
