An exponential equation is represented as:
, where b represents rate
- Exponential growth:
,
and 
- Exponential decay:

- Neither:

An exponential equation is said to represent growth, if the rate is greater than 1, while it represents decay if the rate is less than 1.
This means that:
,
and
represent exponential growth because 5, 4.2 and 1.3 are greater than 1
Also,
represents exponential decay because 0.28 is less than 1
While
is not an exponential function

Step-by-step explanation:
<span>-3|15 - s| + 2s^3
=</span><span>-3|15 - (-3)| + 2(-3)^3
= </span><span>-3|18| -54
= -54 - 54
= -108</span>
