We cannot determine the cost of the tiles from the given information, so the question cannot be answered.
X = 4, -2 that should be the roots(zeros) of the function.
Put the equation given in the form

The center will be (-f, -g)
1,2,4 & 8
12*2<span> = 24</span>
32*2<span> = 64 </span>
44*2<span> = 88 </span>
6*4 = 24
16*4 = 24
<span>etc. </span>
