Find Derivative of f: First, let's find the derivative of the function f with respect to x.f(2x−33)=x+42x+3To find f′(x), we need to differentiate both sides with respect to x.
Apply Quotient Rule: Differentiate the right side using the quotient rule: (v′u−uv′)/v2 Let u=(2x+3) and v=(x+4)u′=2 and v′=1
Calculate f′(x): Now apply the quotient rule:f′(2x−33)=(x+4)2[(x+4)(2)−(2x+3)(1)]= (x+4)22x+8−2x−3= (x+4)25
Find x for f′(1): We need to find f′(1), but we have f′(2x−33). So we need to find the x that makes 2x−33 equal to 1.Set 2x−33=1 and solve for x.2x−3=3f′(1)0f′(1)1
