Answer:
Step-by-step explanation:
Given:
The magnitude, v=12
The angle 
it makes with the positive x-axis =
Now for a vector (x,y)
; and
Therefore:
Similarly:
Recall that:
Therefore: 
The vector in the form ai+bj is therefore:
<h3>
Answer: Reflect over the y axis</h3>
=====================================================
Explanation:
We have these two given functions
The change is that the x has been replaced with -x
We can say
f(x) = x+7
f(-x) = -x+7 ... replace each x with -x
g(x) = f(-x)
g(x) = -x+7
When we replace x with -x, we're flipping the x inputs from positive to negative, and vice versa. This visually will reflect the line over the vertical y axis. A point like (1,8) on f(x) reflects over to (-1,8) on g(x).
As another example, the point (-5,2) on f(x) reflects over the y axis to arrive at (5,2) on the g(x) function.
