Which graph or graphs appear to show a sinusoid ?
2 answers:
<h2>
Answer: </h2>
Option: D is the correct answer.
D. I and III only
<h2>
Step-by-step explanation: </h2>
The graph of a sinusoidal function is a smooth periodic graph. The graph is continuous all over the x-axis and also it repeats itself after every fixed interval. From the graph that is provided to us we observe that the graph I is a sinusoidal graph since it is similar to a graph of sine graph.
Also, the graph II is not a continuous graph and hence it can't be a graph of sinusoidal graph.
Also, graph III is similar to a graph of sine function and hence it represent a graph of a sinusoidal graph.
Answer:
D
Step-by-step explanation:
Sinusoid graphs look like regular waves.
It is obvious that only I and III look like waves.
II is known as a stepwise function.

Step-by-step explanation:
Sorry for the hand writing. But you want to factor out a 4y^2 which will result in (9y^2-1). Then you will factor out the equation in parentheses to (3y-1)(3y+1). Don’t forget to put the 4y^2 out front!
