Answer: D
Step-by-step explanation:
The graph is narrower, so the coefficient of has an absolute value more than 1.
- Eliminate B and C.
Also, because g(x) opens down, the coefficient of is negative.
- Eliminate A.
This leaves D as the answer.
Answer:
Option C.
Step-by-step explanation:
If a vertical line intersects the x-axis at point (c,0), then the equation of line is x=c.
From the given figure it is clear that it is a vertical line and it intersects the x-axis at (-1,0). There are infinite values of y at x=-1.
So, the equation of given line is
Therefore, the correct option is C.
The sinusoidal function that passes through (0,-6), has a period of 12 and an amplitude of 3 will be y = 3 sin 12x - 6.
What is a sinusoidal Function?
It is a function that repeats itself in a particular time interval.
The equation is given as
y = Asin (ωx + Ф) + k
We have
Amplitude (A) = 3
Period (ω) = 12
Phase difference (Ф) = 0
Then the equation will be
y = 3 sin 12x + k
The function is passing through (0, -6). Then we have
-6 = 3sin (12 × 0) + k
-6 = k
Then the equation will be
y = 3 sin 12x - 6
