dy/dx = Ky^(1/2) K is a constant
dy/y^(1/2) = Kdx
Integrate
2y^(1/2) = Kx + C
Use your points to find K and C --- start with (0,1) to find C
The the other to find K
The rate of change of y is proportional to sqrt(y). if the graph of y passes through the points (0, 1) and (2, 4), find y to the nearest integer when x = 6.7.
This one i have no idea how to start or even how to do it, please help.
Thanks in advance.
