Determining exponential growth and decay in exercise, use the given information to write an exponential equation for y. does the function represent exponential growth or exponential decay?
dy/dt = -2/3y, y = 20 when t = 0

Exponential decay

Step-by-step explanation:

We are given that

y=20 when t=0

Taking integration on both sides then we get

Using formula  

Using formula

Substitute y=20 and t=0

Substitute the value of C

When t tends to infinity then

When time increases then the value of function decrease

Hence, the  function is exponential decay.
