When a chemical reaction occurs, molecular bonds are broken and other bonds are formed to make different molecules. For example, the bonds of two water molecules are broken to form hydrogen and oxygen. Energy is always required to break a bond, which is known as bond energy.

What is the percent rate of change in function y = \((0.99)^x\)? Determine whether the function represents exponential growth or
storchak [24]

Answer: The correct answer is 1%: exponential decay.

Explanation: We are given a function:

y=(0.99)^x   ...(1)

To determine the percentage rate of change in function, we compare the given function with the general form of exponent function, which is:

y=a(1+r)^x    ...(2)

Comparing both the equations, we get:

1+r=0.99

r=-0.01

We take 'r' in percentage, so converting this above value in percentage, we get:

r=-0.01\times 100=-1\%

As the value of 'r' is negative, it means that the exponent is decaying, so the percentage rate of change in function will be 1% and it will be exponential decay.
