WebNov 19, 2024 · The derivative f ′ (a) at a specific point x = a, being the slope of the tangent line to the curve at x = a, and. The derivative as a function, f ′ (x) as defined in Definition 2.2.6. Of course, if we have f ′ (x) then we can always recover the derivative at a specific point by substituting x = a. WebDec 2, 2016 · 2 Answers. You should consider the function f ( x 2) as a function of x, so you should look at it as h ( x) = f ( x 2), which you can see as h ( x) = f ( g ( x)) = f ∘ g ( x) where g ( x) = x 2. Thus h ′ ( x) = ( f ( x 2)) ′ = g ′ ( x) f ′ ( g ( x)) = 2 x f ′ ( x 2) Let u = x 2. Then, f ( x 2) = f ( u). You want to differentiate f ...
