For f(x)=x2f(x) = x^2f(x)=x2 the derivative is f′(x)=2xf'(x) = 2xf′(x)=2x.
A paper writes the same function as y=x2y = x^2y=x2 and reports three quantities, each in a different notation:
A=dydx∣x=5,B=ddx(x2)∣x=−3,C=f(4)A = \left.\frac{dy}{dx}\right|_{x = 5}, \qquad B = \left.\frac{d}{dx}\left(x^2\right)\right|_{x = -3}, \qquad C = f(4)A=dxdyx=5,B=dxd(x2)x=−3,C=f(4)
What is A+B+CA + B + CA+B+C?
Select all that apply.
