:)
C.supplementary is the right one
Assuming the sequence goes on like this 11,-33,99,-297,891,...,
its general formula is

So, the 9th term is
This system has one solution y=8x+9, y=x^2+4x+13. What is the y coordinate
y=8x+9<= y=8x+9 <== 8x+9: m=8
y=x^2+4x+13<= y <==x^2+4x+13: minimum (-2,9)
y=8x+9 and y.No solution
