Since the functions are not included, I can help you with some examples and a general explanations which will help you to solve this kind of problems.
1) Assumption: all the functions that are considered are linear.
That means that f(x) = x is the parent function, and you can obtain the other functions by a set of transformations (translation and scalation) of the parent function.
2) Example 1: y = x + a
This is a special case of adding a constant to the function.
In this case, the graph of the new function is the graph of the parent function shifted a units upward.
3) Example: y = 5x
This is a special case of multiplying the function times a constant.
The result is streching the graph vertically by the same scale factor.
4) Example: y = (1/5)x - 8
In this case, the graph of y is obtained by scaling the parent function f(x) = x by 1/5 (which results in compressing the parent function vertically) and shifting the parent function 8 units downward.

Step-by-step explanation:
Combine like terms, in this case there is only x

3 * (-2)ⁿ⁻¹
n = 1; 3 * (-2)¹⁻¹ = 3 * (-2)⁰ = 3 * 1 = 3
n = 2; 3 * (-2)²⁻¹ = 3 * (-2)¹ = 3 * (-2) = -6
n = 3; 3 * (-2)³⁻¹ = 3 * (-2)² = 3 * 4 = 12
n = 4; 3 * (-2)⁴⁻¹ = 3 * (-2)³ = 3 * (-8) = -24
n = 5; 3 * (-2)⁵⁻¹ = 3 * (-2)⁴ = 3 * 16 = 48
The sum is:
3 + (-6) + 12 + (-24) + 48 = 3 - 6 + 12 - 24 + 48 = 33
