Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=2600(0.3)^x y=2600(0.3) x

Decay function, 70% per year.

Step-by-step explanation:

A general exponential function is defined as

    ...(1)

where, a is initial value, |r| is rate of change and x is time in years.

If r>0, then it is a growth function and if r<0, then it is a decay function.

The given function is

It can be rewritten as

    ...(2)

On comparing (1) and (2), we get

Since r<0, therefore the given function is a decay function.

Therefore, the given function decreasing by 70% per year.

c

-by-step explanation:

it would be c

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem
