You can expand the brackets first in the derivate to get 3x^2 +x

To get the y equation, you integrate. Integrating 3x^2 gives you x^3, while integrating x is x^2 /2. Dont forget the C.

So now you have the equation
Y= x^3 + x^2 /2 + C

Substitute x= 2, y=4 and you can find C to substitute to the equation

Hope it helps! Go try it
