Answer:

Decay

Step-by-step explanation:

We are given an equation y=100(1-0.5)^t

We need to say about decay or growth of exponential function.

Exponential function: y=a\cdot b^x

Where,

  • a is initial value of exponential function.
  • b is decay or growth of function

For decay: 0<b<1

For growth: b>1

Now we rewrite the equation into this form

y=100(1-0.5)^t

Changes to

y=100(0.5)^t

Here, b=0.5 < 1

Therefore, The given function would be decay.

Thus, y=100(1-0.5)^t is deacy.
