Question

Calculate $\frac{\partial f}{\partial x}$, $\frac{\partial f}{\partial y}$, $\frac{\partial f}{\partial x}(1, -1)$, and $\frac{\partial f}{\partial y}(1, -1)$ when defined. (If an answer is undefined, enter UNDEFINED.) $\qquad f(x, y) = e^{0.7xy}$ $\frac{\partial f}{\partial x} = 0.7y \cdot e^{0.7xy}$ $\frac{\partial f}{\partial y} = 0.7x \cdot e^{0.7xy}$ Round your answers to 4 decimal places. $\frac{\partial f}{\partial x}(1, -1) = $ $\frac{\partial f}{\partial y}(1, -1) = $

          Calculate $\frac{\partial f}{\partial x}$, $\frac{\partial f}{\partial y}$, $\frac{\partial f}{\partial x}(1, -1)$, and $\frac{\partial f}{\partial y}(1, -1)$ when defined. (If an answer is undefined, enter UNDEFINED.)
$\qquad f(x, y) = e^{0.7xy}$
$\frac{\partial f}{\partial x} = 0.7y \cdot e^{0.7xy}$
$\frac{\partial f}{\partial y} = 0.7x \cdot e^{0.7xy}$
Round your answers to 4 decimal places.
$\frac{\partial f}{\partial x}(1, -1) = $
$\frac{\partial f}{\partial y}(1, -1) = $

Calculate (∂ f)/(∂ x), (∂ f)/(∂ y), (∂ f)/(∂ x)(1, -1), and (∂ f)/(∂ y)(1, -1) when defined. (If an answer is undefined, enter UNDEFINED.)
f(x, y) = e^0.7xy
(∂ f)/(∂ x) = 0.7y · e^0.7xy
(∂ f)/(∂ y) = 0.7x · e^0.7xy
Round your answers to 4 decimal places.
(∂ f)/(∂ x)(1, -1) =
(∂ f)/(∂ y)(1, -1) =
