There exists a 3 4 matrix with rank 4.
L18 - 2 Theorem (The Chain Rule): If g is differentiable at x and f is differentiable at g(x), then the composite function F = f ◦ g = f(g(x)) is differentiable and ▯ F (x)= Chain Rule (second version: rate of change) If y = f(u)ad u = g(x)aediniluci,en √ ex. Find h (x)fr h(x)= x +2 x − 3. x 5 ▯ ex. If f(x)=( 2 e − 3x) ,fi nd f (0).
