Math Problem Statement

Given : f(x)=x²-2x+2 at f (2x-3)

Solution

To solve for f(2x3)f(2x - 3) given the function f(x)=x22x+2f(x) = x^2 - 2x + 2, we'll substitute 2x32x - 3 in place of xx in the function.

  1. Start with the original function: f(x)=x22x+2f(x) = x^2 - 2x + 2

  2. Substitute 2x32x - 3 for xx: f(2x3)=(2x3)22(2x3)+2f(2x - 3) = (2x - 3)^2 - 2(2x - 3) + 2

  3. Expand and simplify: (2x3)2=(2x3)(2x3)=4x212x+9(2x - 3)^2 = (2x - 3)(2x - 3) = 4x^2 - 12x + 9 2(2x3)=4x+6-2(2x - 3) = -4x + 6

  4. Combine all the terms: f(2x3)=4x212x+94x+6+2f(2x - 3) = 4x^2 - 12x + 9 - 4x + 6 + 2 f(2x3)=4x216x+17f(2x - 3) = 4x^2 - 16x + 17

So, f(2x3)=4x216x+17f(2x - 3) = 4x^2 - 16x + 17.
