<span>Stimuli that are perceived subliminally is called Subliminal
Stimuli; literally considered as “below threshold” that is contrary to
supraliminal stimuli or above threshold. These are any sensory stimuli below an
individual’s threshold for concious perception and this subliminal stimuli
activate specific regions of the brain despite participants being unaware through
visual stimuli may be quickly appear suddenly before an individual can process
them or it will appear suddenly and then masked thereby interrupting the
processing and the audio stimuli may be played below audible columes or masked
by other stimuli. </span>

Answer: g(x) = 2sin(x)+3</h3>
=============================================
Explanation:
We start with y = sin(x) or f(x) = sin(x). Recall that y = f(x) since both are outputs.
Vertically stretching by a factor of 2 means we multiply each y value by 2.
This means,
y = sin(x)
2y = 2sin(x)
Then we shift 3 units up. So we add 3 to the y coordinate
2y+3 = 2sin(x)+3
---------------------------------------------------
We can track an example point to see this movement in action. For instance, let's focus on the point (pi/6,1/2) which is on f(x). I'm in radian mode.
Stretching f(x) vertically by a factor of 2 means (pi/6,1/2) moves to (pi/6, 1) after the stretching occurs. I multiplied the y coordinate by 2, and kept the x coordinate the same.
Then we shift up 3 units to go from (pi/6, 1) to (pi/6, 4). You add 3 to the y coordinate and keep the x coordinate the same. Note that plugging x = pi/6 into g(x) = 2sin(x)+3 leads to 4.
An effect may be: unable to reproduce
I’m pretty sure it would be B but it could also be D
