This is the entire question:
A curve has the equation y=(x+2)√(x1).
i)Show that dy/dx = kx/√(x1) and find k
ii)Hence, evaluate limit 2 to 5
∫ kx/√(x1)dx
My answer: first part, i have already shown, and k is equals to 3/2
I don't get the second part though, it says evaluate ∫ kx/√(x1)dx, isnt that equals to ∫ (dy/dx) dx, which is equals to y? o.o

correct. Evaluate y(5)y(2)
