Explanation Definition used: Partial derivatives: “The partial derivative of f with respect to x is the derivative of f obtained by treating x as a variable and y as a constant. The partial derivative of f with respect to y is the derivative of f obtained by treating y as a variable and x as a constant”. Calculation: The given multivariable function f ( x , y ) = − 3 x 4 y 3 + 10 . Treat y as a constant and x as a variable to find the Partial derivative of the function f ( x , y ) with respect to x , f x ( x , y ) = ∂ ∂ x ( − 3 x 4 y 3 + 10 ) = ∂ ∂ x ( − 3 x 4 y 3 ) + ∂ ∂ x ( 10 ) = − 3 y 3 ∂ ∂ x ( x 4 ) + 0 = − 12 x 3 y 3 Therefore, the partial derivative with respect x is, f x ( x , y ) = − 12 x 3 y 3 . Obtain the partial derivative f y ( x , y ) . Treat x as a constant and y as a variable to find the Partial derivative of the function f ( x , y ) with respect to x , f y ( x , y ) = ∂ ∂ y ( − 3 x 4 y 3 + 10 ) = ∂ ∂ y ( − 3 x 4 y 3 ) + ∂ ∂ y ( 10 ) = − 3 x 4 ∂ ∂ y ( y 3 ) + 0 = − 3 x 4 ( 3 y 3 − 1 ) Simplify further and obtain the partial derivatives, f y ( x , y ) = − 3 x 4 ( 3 y 2 ) = − 9 x 4 y 2 Therefore, the partial derivative with respect y is, f y ( x , y ) = − 9 x 4 y 2
