Question

Which graph or graphs appear to show a sinusoid? < Help me please ASAP !

Answer 1

Answer: c

Step-by-step explanation: A P E X :)

Answer 2

C. II and III only is correct.

Explanation:

We are given the graphs of the functions and are required to find the sinusoidal graph.

According to the options, we see that,

Graph I can never be the graph of a sine function as it is not repeating.

Graph II and III are periodic and also can be obtained by applying some translations to the parent function
`f(x)=\sin x`

Hence, we get that,

Graph II and III represents sinusoidal functions.

Thus, option C i.e. II and III only is correct.
