Full solution

Q. Find (fg)(0)(f \circ g)(0). f(x)=6xf(x) = 6x, g(x)=x2+4xg(x) = x^{2} + 4x
  1. Understand Composition of Functions: First, we need to understand what the composition of functions (f@g)(x)(f@g)(x) means. It means that we first apply the function gg to xx, and then apply the function ff to the result of g(x)g(x). So, (f@g)(x)=f(g(x))(f@g)(x) = f(g(x)).
  2. Find g(0)g(0): Given the functions f(x)=6xf(x) = 6x and g(x)=x2+4xg(x) = x^2 + 4x, we need to find g(0)g(0) first, since we are looking for (f@g)(0)(f@g)(0).
  3. Calculate g(0)g(0): To find g(0)g(0), we substitute xx with 00 in the function g(x)g(x): g(0)=02+40g(0) = 0^2 + 4\cdot0.
  4. Find f(g(0))f(g(0)): Calculating g(0)g(0) gives us g(0)=0+0g(0) = 0 + 0, which simplifies to g(0)=0g(0) = 0.
  5. Calculate f(0)f(0): Now that we have g(0)g(0), we need to find f(g(0))f(g(0)). Since g(0)=0g(0) = 0, we need to find f(0)f(0).
  6. Final Result: To find f(0)f(0), we substitute xx with 00 in the function f(x)f(x): f(0)=6×0f(0) = 6 \times 0.
  7. Final Result: To find f(0)f(0), we substitute xx with 00 in the function f(x)f(x): f(0)=6×0f(0) = 6\times0.Calculating f(0)f(0) gives us f(0)=0f(0) = 0, which means that (f@g)(0)=f(g(0))=f(0)=0(f@g)(0) = f(g(0)) = f(0) = 0.
