X^2 + 30x + 21
= ( x + 15)^2 - 225 + 21
= (x + 15)^2 - 204
Its D minimum at -204
Answer:
see the explanation
Step-by-step explanation:
we know that
If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image
If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image
so
<u><em>Verify each value</em></u>
1) -4


therefore
The dilation produces an expansion of the original image
2) 0.25


therefore
The dilation produces a contraction of the original image
3) -2/3


therefore
The dilation produces a contraction of the original image
4) 2.3


therefore
The dilation produces an expansion of the original image
