# Chapter 15 - Differentiation in Several Variables - Chapter Review Exercises - Page 835: 17

$$f_x= 2,f_y= 2y.$$

#### Work Step by Step

To calculate the partial derivatives, treat all variables as constant except the variable we are deriving with respect to. Since $f(x,y)=2x+y^2$, then we have $$f_x=\frac{\partial f}{\partial x}=2,$$ $$f_y=\frac{\partial f}{\partial y}=2y.$$
