Answer:

Step-by-step explanation:
<u>Sequential Operations
</u>
Mathematical operations can be done in sequence or in batches if they are of the same type. For example, we can add many terms in one single operation, but we cannot add and multiply in one go, because there are priorities when dealing with products and sums. Same happens with powers.
In our problem we are required to perform a sequence of operations like follows
Add s to t:

Add the result to r

Raise what you have to the 7th power

This is the final result
6
84
91
395
All these are rounded to the nearest whole number
C because that’s what it is
The first choice is correct.
in the first function f(x)=3x-2, the smallest value is when x=-1, y=-5, the largest value is when x=0, y=-2, but it doesn't include -2 because there is no = sign.
in the second function, the smallest value of y is when x=0, y=3, the largest value is y=13, but it doesn't include y=13
-4 + 8 = 4;
4 - 16 = -12;
-12 + 32 = 20;
20 - 64 = -44;
-44 + 128 = 84;
84 - 256 = -172.
The sum of the first 7 terms in this series is -172.
I hope this helps!
