will work on this tonight, just need comparisons because scared
i'll stuff up hey : O
Q1) when x = 1.6
6y^2 +6y=8(1.6) +7=19.8
6y^2 +6y-19.8=0
y=[-6+-sqrt(36-4*6*-19.8)]/12
y=1.3841 or y=negative number (rejected)
At this point, differentiate implicitly with respect to x.
(12y + 6 )(dy/dx) = 8
dy/dx = 0.3538
