Answer:
- (f - g)(x) = x⁴ - x³ - 2x² - 4x + 12
--------------------------
Given
Functions f an g
- f(x) = x⁴ − 4x² + 4
- g(x) = x³ − 2x² + 4x − 8
Find the composite function (f - g)(x)
- (f - g)(x) =
- f(x) - g(x) = x⁴ - 4x² + 4 - (x³ −-2x² + 4x - 8) =
- x⁴ - 4x² + 4 - x³ + 2x² - 4x + 8 =
- x⁴ - x³ - 2x² - 4x + 12
