Answer:
1 and 2) After multiplying (x+y+3)(y+1) we have
- xy+x+y^2+4y+3
Which is an equivalent expression after applying the distributive property.
As we can see we have an one of the variables squared, so we obtain an Parabolic Cillinder
Answer:
1)
2)
3)
Step-by-step explanation:
General form of sin function is
Where A is Amplitude
B is
C is Mid line
1) Given : A sine function has the following key features
Frequency =
Period is
Amplitude= 2
Mid line y= 2
Y intercept (0,2)
This function is NOT a reflection of its parent function of the x-axis
Solution : We put the value in the general form of sin function
A= 2 , , C=2
2) Given : A sine function has the following key features
Period = 4
Amplitude = 3
Mid line y = -1
Y intercept (0,-1)
Solution : We put the value in the general form of sin function
A= 3 , , C=-1
3) Given : A sine function has the following key features
Period =
Amplitude = 2
Mid line y = -12
Y intercept (0,-2)
Solution : We put the value in the general form of sin function
A= 2 , , C=-2
