Transformations are without the equation already in them but I'll tell you what I know.
So your 5th problem is a reflection.
So the main thing is starting from the left of an equation you read the transformation from a point on the graph.
so for example, the first graph, reflects across the Y axis. What makes this the most is it's all linear. So transformations are like...
2x+2 this is really hard to teach as a linear.
okay picture something like this...

since the - is on the inside this means it reflects across the Y axis

since this is on the outside it reflects across the X axis.
try searching YTfor "understanding transformations" it's slightly confusing and I feel I'm too to teach it properly. It took me forever to understand the first I saw too so don't be discouraged.
Answer:

and the interval of the convergence is (-1, 1)
Step-by-step explanation:
To find a power series for the function, centered at c.

If we factorize the denominator, we have:


Thus;





and the interval of the convergence is (-1, 1)
Answer:
degree=5 is your answer of your question
x + y = 18 → 3x + 3y = 54
x - 3y = 22 → x - 3y = 22
4x = 76
4 4
x = 19
x + y = 18
19 + y = 18
- 19 - 19
y = -1
(x, y) = (19, -1)
