ANSWER
EXPLANATION
The given limit is
To evaluate this limit by direct substitution,
We put x=0 in the function.
This implies that that ,
This simplifies to,
This means that as x-values approach zero, the function approaches -1.
The coordinates of point r(-8,0).
<h3>What is midpoint formula in coordinate geometry?</h3>The coordinates of the point r(x,y) which divides the line segment joining the points p(,
) and q(
,
) internally in the ratio :
are
Given that,
Two end points on the line q(-14,0) and s(2,0). point r(x,y) is the partition of the line segment from q to s in a ratio 3:5
= 3 and
= 5
By using the midpoint formula
Hence, The coordinates of point r(-8,0).
