Q. Find the derivative of f(x). f(x)=x+3f′(x)= ______
Identify Function: Identify the function to differentiate.f(x)=x+3Rewrite x+3 as (x+3)21 for easier differentiation.
Apply Chain Rule: Apply the chain rule for differentiation: dxd[u(v(x))]=u′(v(x))⋅v′(x). Let u(x)=x21 and v(x)=x+3. Then, u′(x)=21x−21 and v′(x)=1.
Substitute and Simplify: Substitute back to find f′(x).f′(x)=21(x+3)−21×1Simplify to get f′(x)=2x+31.
