Answer:
= 3a + 7b - 8c
Step-by-step explanation:
In addition of algebraic expressions while adding algebraic expressions we collect the like terms and add them. The sum of several like terms is the like term whose coefficient is the sum of the coefficients of these like terms.
Horizontal Method: In this method, all expressions are written in a horizontal line and then the terms are arranged to collect all the groups of like terms and then added.
(6a + 8b - 7c) + (2b + c - 4a) + (a - 3b - 2c)
= 6a + 8b - 7c + 2b + c - 4a + a - 3b - 2c
Arrange the like terms together, then add.
Thus, the required addition
= 6a - 4a + a + 8b + 2b - 3b - 7c + c - 2c
= 3a + 7b - 8c
Column Method: In this method each expression is written in a separate row such that there like terms are arranged one below the other in a column. Then the addition of terms is done column wise.
6a + 8b - 7c
- 4a + 2b + c
a - 3b - 2c
3a + 7b - 8c
= 3a + 7b - 8c
First of all, let's study each function:
Function A) 
This is a
quadratic function. This type of function is a second-degree polynomial function.
Function B) 
<span>
</span>
This is an
exponential function. This type of function is a non-algebraic function. It's also called <span>transcendental function.
</span>
Function C)<span>

</span>
It's a
straight line with slope equal to 100 and without y-intercept.
Function D)
<span>
It's a
cubic function. It's a third</span>-degree polynomial function.
So from the figure it is obvious that
the function that grows at the fastest rate is the exponential function B). In fact, an exponential function always grows more quickly than a polynomial function.
