Answer:
Step-by-step explanation:
A local maximum or local minimum is the point where the tangent drawn to it is parallel to the x axis.
The crest of a wave is local maximum and the trough of wave is local minimum.
Here, in the graph, there are 2 troughs and 1 crest.
The crest is at . So, the local maximum is at
.
The interval of the local maximum is between and
.
So, the option that matches with the above interval is .
2x-3y-5=0
2x-5=3y
3y=2x-5
y=
Gradient of line 1 =
Gradient of line 2;
2x-5=3y
3y=2x-5
y=
Gradient of line 1 =
Gradient of line 2;
