Answer:

a=5\\ \\b=0.5

Step-by-step explanation:

Given the exponential decay function y=5\cdot (0.5)^x

When x=0, then

y=5\cdot (0.5)^0=5\cdot 1=5,

so the initial amount is a=5

The exponential decay function y=a\cdot b^x has the decay factor b.

In your case, the eexponential decay factor is b=0.5
