The answer is 4.
8/x +13 = y --------> y * 2 = 30
divide 2 on both sides so y = 15
8/x + 13 = 15
- 13 - 13
8/x = 2
x =4
Let's start with our parent function:
f(x) = sin x
One cycle on this graph occurs between 0 and 2π. Therefore, our b-value is one.
There is no vertical shift up. The sinusoidal axis is along y = 0.
The wave is not inverted, it starts at the origin and rises on both the y and x axis. Thus there is no negative value before the function.
The amplitude of the wave is 3. A normal sine wave rises to a maximum of 1, but this is multiplied by 3.
f(x) = 3 sin x
There are an infinite amount of equations that could be used to represent this graph, but this is perhaps the most intuitive.
Coefficient of y = 3
Solution:
Given expression is 2 · 4 + 3y.
To find the coefficient of y:
Coefficient means the number in front of the variable or term.
Here, the number in front of y is 3.
2 and 4 are not in front of y, they are separate term.
So, Coefficient of y = 3.
Hence the coefficient of y in the expression 2 · 4 + 3y is 3.
