a) x + 1
b) x - 1
Answer:
Below
Step-by-step explanation:
The equation of the red graph is f(x) = x^2 + 3
The +3 without the presence of a bracket tells us that a vertical translation of 3 units upward has been applied to the parent graph. If you look at the picture you can see that the red graph has moved up 3 units from the origin.
If the 3 were to be inside a bracket, it would indicate that there has been a horizontal translation either left or right. The graph has not moved horizontally therefore none of the options with the brackets are correct.
Hope this helps! Best of luck <3
Multiply the original DE by xy:
xy2(1+x2y4+1−−−−−−−√)dx+2x2ydy=0(1)
Let v=xy2, so that dv=y2dx+2xydy. Then (1) becomes
x(y2dx+2xydy)+xy2x2y4+1−−−−−−−√dxxdv+vv2+1−−−−−√dx=0=0
This final equation is easily recognized as separable:
dxxln|x|+CKxvKx2y2−1K2x4y4−2Kx2y2y2=−dvvv2+1−−−−−√=ln∣∣∣v2+1−−−−−√+1v∣∣∣=v2+1−−−−−√+1=x2y4+1−−−−−−−√=x2y4=2KK2x2−1integrate both sides
