WebFinal answer. Step 1/3. Let the function is. f ( x, y) = e − 3 x 2 − y 2 + 5 x + 4 y. Differentiate the right side of the equation. e − 3 x 2 − y 2 + 5 x + 4 y ( − 6 x + 5) Reform the equation by setting the left side equal to the right side. z ′ = e − 3 x 2 − y 2 + 5 x + 4 y ( − 6 x + 5) Replace z ′ with d z d x.
