dy/dx when x = 1 is (4y + 3) / 2.
Step-by-step explanation:
x^3 + 2x^2y - 4y=7
Using implicit differentiation:
3x^2 + 4xy + 2x^2. dy/dx - 4 dy/dx = 0
2x^2. dy/dx - 4dy/dx = - 3x^2 - 4xy
dy/dx = (-3x^2 - 4xy) / (2x^2 - 4)
When x = 1:
dy/dx = (-3 - 4y) / - 2
= - 1 (4y + 3) / - 2
(4y + 3) / 2 (answer).
