A) 4/36, or 1/9
b) 1-1/9=8/9
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.
Answer:
D) 1541
Step-by-step explanation:
I like to answer it w without deriving the formula of f(g(x)). So, we go this way, you firstly have to find g(7) which will be equal to 3 * 7 - 5 = 16.
And then you find f(16) = 6*16*16+5 = 1541. That's all.
Answer:
Greatest to least
28/13, 1, 6/20, -0.4
Step-by-step explanation:
I would say c, 600 inches. Because I subtracted 621-28 and got about 600. Because they are looking for the value of what was left for the 19 Years. And you could then fully eliminate D because it can’t be more that 621 because that’s how much rainfall they got in 20 years. And so since you know that one of the years is 28 inches of rainfall, you could then subtract to get how many inches of rainfall for the rest of the 19 years
