Table 1 is proportional as y=6x
Table 2 is not proportional
first factor out -4
-4(x^2 + 7x + 12)
then you can factor what is in parenthesis
-4(x+4)(x+3)
Answer:$4.36

Answer:
D) y = 1/4 x^2
Step-by-step explanation:
For these functions, the leading coefficient can be considered to be either ...
the vertical scale factor (larger ⇒ narrower)
the square of the inverse of the horizontal scale factor.
In the latter case, the horizontal scale factor will be larger (wider) when its inverse and the square of its inverse are smaller.
Either way, you're looking for the smallest leading coefficient: 1/4.
