Answer:
see below for a graph
Step-by-step explanation:
Completing the square for x and y terms can help you put this in the standard form.
(x^2 +10x) +(y^2 +6y) = -18
(x^2 +10x +25) +(y^2 +6x +9) = -18 +25 +9 . . . . add square of half linear coefficient
(x +5)^2 +(y +3)^2 = 16 . . . . . . . circle centered at (-5, -3) with radius 4
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.
