Question

how to find the derivative of f(x) = 6x + 2 at x = 1.

Answer 1

if you are looking at how things change relatively - which is why derivatives are important - then:

\(\dfrac{d}{dx} x^n = n \; x^{n-1}\)


and constants don't change.

so

\(\dfrac{d}{dx} C= \; 0\)

that could be pretty cryptic, or very obvious, so tag me if you need more input.
