Question

$y = - 3 x ^ { 2 } - x$ between  x=5  and  x=6 
A)  $\frac { 1 } { 2 }$
B)  -2 
C) -$\frac { 1 } { 6 }$
D)  -34

To find the change in $y$ between $x = 5$ and $x = 6$, we calculate $y$ at both points and subtract. For $x = 5$, $y = -3(5)^2 - 5 = -75 - 5 = -80$. For $x = 6$, $y = -3(6)^2 - 6 = -108 - 6 = -114$. The change in $y$ is $-114 - (-80) = -34$.

y=−3x2−xy = - 3 x ^ { 2 } - xy=−3x2−x

$y = - 3 x ^ { 2 } - x$
