Given the equation :

Let: y = sin x
So,

the given equation will be:

Solve for y, take 3y as a common:

so,

Note: the range of sine function is [ -1, 1]
So, sin x = 2 ( is rejected)
So, the answer will be: x ={ 0 , pi }
1/7, 6/7, 1 1/7, 1 2/3, and 18/9
1×5 or 5×1 would be a factual of it
Answer:
Not a function, because there are more than one of the same x-intercept which makes a vertical line.
Step-by-step explanation:
Slope = change in y / change in x
slope = (6-3) / (8-2)
Slope = 3/6
slope = 1/2
