Question

Dadas las siguientes funciones encuentre: f (x) + g (x); f (x) - g (x); f (x) ∙ g (x); f (x) / g
(x)
f(x) = x - 6
g(x) = x2 - 36

Answer 1

suma

x- 6+ x^2- 36

= x^2+x-42

RESTA

x-6-(x^2-36)

= x- 6- x^2+ 36

= x- x^2+ 30

Multiplicacion

(x-6)(x^2-36)

= x^3- 36x- 6x^2+ 216

= x^3- 6x^2- 36x+ 216

Division

f(x)/g(x)= x-6/x^2-36 = (x-6)/ (x+6) (x-6)= x+6
