Answer:
D
Step-by-step explanation:
Solution:-
The standard sinusoidal waveform defined over the domain [ 0 , 2π ] is given as:
f ( x ) = sin ( w*x ± k ) ± b
Where,
w: The frequency of the cycle
k: The phase difference
b: The vertical shift of center line from origin
We are given that the function completes 2 cycles over the domain of [ 0 , 2π ]. The number of cycles of a sinusoidal wave is given by the frequency parameter ( w ).
We will plug in w = 2. No information is given regarding the phase difference ( k ) and the position of waveform from the origin. So we can set these parameters to zero. k = b = 0.
The resulting sinusoidal waveform can be expressed as:
f ( x ) = sin ( 2x ) ... Answer
if I read your question correctly, you can use multiplication to get the same answer with division. for example;
2 x 2 = 4; 4 divided by 2 = 2.
8 x 4 = 32; 32 divided by 8 = 4; 32 divided by 4 = 8.
5 x 6 = 30; 30 divided by 5 = 6; 30 divided by 6 = 5
hope this helped! :D
Obviously the Correct Step would give him the correct answer lol !
But, here he goes !!



✓ So, h = 5 ; k = 11 would make him correct
X^2 x 8x -3x^2 +5 x 8x -5 x 3
8x^3 -3x^2 +40x -15
