Step-by-step explanation:
Answer:
f(8)=-161
Step-by-step explanation:
f(x) = -3x^2 + 3x + 7
f(x) = -3x2 + 3x + 7
f(8)= -3(8)^(2) + 3(8) + 7= -192+24+7=-161
Answer:
Dilate by a scale factor of 0.5 with the origin as the center of dilation.
Rotate 90° clockwise about the origin
Step-by-step explanation:
Polygon ABCD:
- A = (-2, 4)
- B = (-8, 2)
- C = (-4, 8)
- D = (-2, 6)
Dilate by a scale factor of 0.5 with the origin as the center of dilation (pink polygon on attached diagram).
This means multiply the x and y values of the points by 0.5:
A → (-1, 2)
B → (-4, 1)
C → (-2, 4)
D → (-1, 3)
Rotate 90° clockwise about the origin: (x, y) → (-y, x)
A' = (-2, 1)
B' = (-1, 4)
C' = (-4, 2)
D' = (-3, 1)
So the transformations are:
- Dilate by a scale factor of 0.5 with the origin as the center of dilation.
- Rotate 90° clockwise about the origin.
