Use the implicit differentiation to find the derivatives of
the given functions.
1. x^2 + y = 1
= 2x + y dy/dx = 1
-2x -2x
= y dy/dx = -1x
y y
Final Answer = dy/dx = -x/y
2. x^2 - 4x - y = 7
= 2x – 4x – y dy/dx = 7
-2x -2x
= -4x- y dy/dx = 5x
4x 4x
= y dy/dx = 9x
y y
Final Answer= dy/dx = 9x/y
3. 3x^3 + y^2 = 9
=9x^2 + 2y dy/dx = 9
=18x + 2y dy/dx = 9
