I'm assuming the line goes through the points (1,3) and (3,9). If that's not correct, ignore this answer.
The slope of the line is 3x. The full equation of the line is y = 3x
Answer:
It's A, -16.
Step-by-step explanation:
solve by moving all terms with d to the left hand side
subtract 8d from both sides
d + 1 = - 15
- 15 - 1 = -16
-16 = d
for all
, so

Similarly, 
We can of course see the limits are identical by replacing
, so that

You can also rewrite the limands to accommodate the application of l'Hôpital's rule. For instance,

Using the rule, the limit here is

so the overall limit is

Answer:
Bottom left graph
Step-by-step explanation:
Since the y-coordinates are the same, but the x-coordinates are opposites, it is a reflection across the y axis.
Therefore, the bottom left graph is correct.
