Q. Given the function f(x)=4x23 f(x)=-4 x^{2}-3 , then what is f(x1) f(x-1) as a simplified polynomial?\newlineAnswer:
  1. Substitute x1x-1: Substitute (x1)(x-1) for xx in the function f(x)=4x23f(x)=-4x^2-3.\newlinef(x1)=4(x1)23f(x-1) = -4(x-1)^2 - 3
  2. Expand square: Expand the square (x1)2(x-1)^2.(x1)2=x22x+1(x-1)^2 = x^2 - 2x + 1
  3. Substitute expanded square: Substitute the expanded square into the function.\newlinef(x1)=4(x22x+1)3f(x-1) = -4(x^2 - 2x + 1) - 3
  4. Distribute 4-4: Distribute the 4-4 across the terms in the parentheses.\newlinef(x1)=4x2+8x43f(x-1) = -4x^2 + 8x - 4 - 3
  5. Combine constant terms: Combine the constant terms 4-4 and 3-3.f(x1)=4x2+8x7f(x-1) = -4x^2 + 8x - 7
