i have no clue im sorry man but i need points. i hope someone helps you

Above, I changed the fraction form of x and y into exponential form so it is easier to see the differentiation. Now, we can differentiate:

Now that we have dy/dx, we can plug in the x, which is 4, and the y, which is 4/19. We know these values of x and y because your question stated y(4) = 4/19.
The first step would be to add 3x and 2x i believe but I am not sure
