Integrations and complex functions

Integrations and complex functions Integrations and complex functions ,Let 𝑓(𝑥) = √𝑥 − 3 and 𝑔(𝑥) = (𝑥 − 3)2, find (𝑔𝑜𝑓)(7). solutions Answer: gof (7) = 1 f (7) = √x-3 =√4 =2. Work: (gof)(7)= g(f(7))= f(7)= g(2) g(2)= (x-3)2 = (2-3)2 =(-1)2 =1. Integrations and complex functions, Let 𝑓(𝑥) = √𝑥 − 3 […]

Mathematics: Inverse functions and calculations

  Question: Determine the inverse of the function: ℎ(𝑥) = 2𝑥−3/(1−𝑥)   Solution and steps followed Answers: f-1 (x)= x+3 2+x   Work: we replace h(x) with y, y= 2x-3 1-x We then swap the y for x, x = 2y–3 1-x Solve for y, x(1–y) = 2y–3 x-xy= 2y–3   2y+xy = x +3.
