Choose the correct answer below.
A.
Since each limit approaches
66,
it follows that the limits are equal.
B.
Since
StartFraction x squared minus 4 x minus 12 Over x minus 6 EndFraction equals x plus 2x2−4x−12x−6=x+2
whenever
xnot equals≠66,
it follows that the two expressions evaluate to the same number as x approaches
66.
C.
The numerator of the expression
StartFraction x squared minus 4 x minus 12 Over x minus 6 EndFractionx2−4x−12x−6
simplifies to
x plus 2x+2
for all x, so the limits are equal.
D.
The limits
ModifyingBelow lim With x right arrow 6 StartFraction x squared minus 4 x minus 12 Over x minus 6 EndFractionlimx→6 x2−4x−12x−6
and
ModifyingBelow lim With x right arrow 6 left parenthesis x plus 2 right parenthesislimx→6 (x+2)
equal the same number when evaluated using direct substitution.
