50 points if you can me ! a student says that the function f(x)-=(1/0.5)^x is an exponential decay function. explain the students error

Step-by-step explanation:

f(x)=(1/0.5)^x

Lets simplify what is in the parentheses

1 / .5 = 2

f(x)=(2)^x

Since 2 > 1

 This function grows

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
