<h2>
Hello!</h2>
The answer is:
<h2>
Why?</h2>
Since we don't have the function equation, but we have the graphic, we can use it to know what value of x makes the function equal to 0.
Finding what values of x does means that we should find where the function intercepts the x-axis.
From the graphic, we can see that the functions intercepts the x-axis at
Have a nice day!
Answer:
Options B and D.
Step-by-step explanation:
The general form of sine function
where, |A| is amplitude, is period, is phase shift and D is y-intercept.
The general form of cosine function
where, |A| is amplitude, is period, is phase shift and D is y-intercept.
In function,
Amplitude :
y-intercept : -1
In function,
Amplitude :
y-intercept : -1
In function,
Amplitude :
y-intercept : 0
In function,
Amplitude :
y-intercept : -1
Therefore, the correct options are B and D.
