"sea f(x) = 2x - 1 y g(x) = x2 hallar (f o g) (x) + (g o f) (x)"?
"sea f(x) = 2x - 1 y g(x) = x2 hallar (f o g) (x) + (g o f) (x)".
En resumen
Fog(x) = 2(x²) - 1 = 2x² - 1 gof(x) = (2x - 1)² = 4x² - 4x + 1 suma : (2x² - 1) + (4x² - 4x + 1) = 6x² - 4x reduciendo fog(x) + gof(x) = 2x(3x - 2).

Fog(x) = 2(x²) - 1 = 2x² - 1
gof(x) = (2x - 1)² = 4x² - 4x + 1
suma :
(2x² - 1) + (4x² - 4x + 1) = 6x² - 4x
reduciendo
fog(x) + gof(x) = 2x(3x - 2).
