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

Answer:
Subtract 23 from both sides
Step-by-step explanation:
This is how algebra works, to get a variable by itself you have to do the opposite to both sides. Hope this helped.
Answer:

Step-by-step explanation:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept(value of x when y = 0).
In this question:
Slope 4, which means that
.
So

Contains point (1,-8).
This means that when
. We replace this into the equation to find b. So



So
