Find the inverse of the following functions f(x)=6-3x g(x)=x+2
astraxan [27]
      f(x) = -3x + 6
          y = -3x + 6
          x = -3y + 6
     x - 6 = -3y
       -3       -3
⁻¹/₃x + 2 = y
⁻¹/₃x + 2 = f⁻¹(x)

 g(x) = x + 2
     y = x + 2
     x = y + 2
x - 2 = y
x - 2 = g⁻¹(x)

Graph ΔABC and its image after a rotation of 180º about the origin.
ValentinkaMS [17]

Answer:

The vertices of image are A'(0,0), B'(-1,-5) and C'(4,-5). The graph of image and preimage is shown below.

Step-by-step explanation:

From the given figure it is noticed that the vertices of  triangle ABC are A(0,0), B(1,5) and C(-4,5).

If a figure rotated at 180º about the origin, then

P(x,y)\rightarrow P'(-x,-y)

The vertices of image are

A(0,0)\rightarrow A'(0,0)

B(1,5)\rightarrow B'(-1,-5)

C(-4,5)\rightarrow C'(4,-5)

Therefore the vertices of image are A'(0,0), B'(-1,-5) and C'(4,-5).

The graph of image and preimage is shown below.
