Answer:
C
Step-by-step explanation:
The red graph is not a direct translation of y = f(x)
If we consider the coordinates of corresponding points on the black graph to those on the red graph
Left set of points
(- 2, - 2 ) → (- 2, - 1 )
middle points
(2, 2 ) → (2, 1 )
right set of points
(4, - 4 ) → (4, - 2 )
Note that in each case the y- coordinate on the red graph is one half the value of the y- coordinate on the black graph, thus
The equation of the red graph is
2y = f(x) → C
since y = f(x)

Answer:
(4, 4)
Step-by-step explanation:
Coordinates of a point (x, y) after dilation with a scale factor k,
Rule to be followed,
(x, y) → k(x, y)
→ (kx, ky)
Coordinates of point T are (8, 8).
Dilation of the point T after dilation with a scale factor of will be,
(8, 8) →
→ (4, 4)
Therefore, coordinates of the image point B' will be (4, 4).
