Question 558563
Presuming a polynomial *[tex \LARGE y = 2x^2 + 3^2 = 2x^2 + 9].


It's usually regarded as a "derivative," not "slope" (since the slope through a tangent line on the graph is not constant). We denote the derivative by dy/dx, in which by the power rule,


*[tex \LARGE \frac{dy}{dx} = 4x]
