The first derivitive is the slope
a positive 1st deriviive is positive slope or increasing
a negaitve 1st derivitive is negative slope or decreasing
the 2nd derivitive tells about the concavity
a negative second derivitive means it is concave down at that point
a positive 2nd derivitive means it is concave up at that point
so
first one is false
2nd is true
3rd is false because it could possibly be a minimum as well
answer is 2nd one
Parallel: line p with slope 2/5
Perpendicular: line n with slope -5/2
the other two would be neither.
Answer:
0.875 is equivalent to 7/8
Leave a thanks if this helped
The slope is -4/1. Hope this helps
