Answer:

Amplitude = 1/2

Period  =  \dfrac23 \pi

Phase shift = \pi (left)

Vertical shift = -3

Step-by-step explanation:

f(x)=-\dfrac12cos(3(x+\pi))-3

y = A sin(B(x + C)) + D

Amplitude is A = 1/2

Period  is \dfrac2B \pi =  \dfrac23 \pi

Phase shift is C= \pi (left)

Vertical shift is D = -3

The form is

\\ \tt\longmapsto f(x)=Asin(B(x+c))+D

where

  • A=Amplitude
  • Period=2π/B
  • Phase shift=c
  • Vertical shift=D

Now compare to our given function

  • Amplitude=-1/3
  • Period=2π/3
  • phase shift=c=π
  • Vertical shift=-3

Can someone please help me with this math question
lora16 [44]

Answer:

C'(4,4)

Step-by-step explanation:

The dilation of quadrilateral ABCD over the origin by a scale factor of 2 has the rule

(x,y)→(2x,2y)

So,

  • A(-3,-1)→A'(-6,-2)
  • B(-1,1)→B'(-2,2)
  • C(2,2)→C'(4,4)
  • D(3,-2)→D'(6,-4)

Hence, the coordinates of the image point C' are (4,4) (see attached diagram for details)
