Question

Dadas las funciones f (x) = 5x – 3 y g (x) = (x+3)/x, determine:
f o g.
g o f.

Answer 1

Respuesta:

Explicación paso a paso:

f (x) = 5x – 3

g (x) = (x+3)/x

fog(x) = 5 . [ (x+3)/x] - 3

fog(x) = (5x - 15)/x - 3

fog(x) = (5x - 15 - 3x)/x

fog(x) = (2x - 15)/x

gof(x) = (5x - 3 + 3)/(5x - 3)

gof(x) = 5x/(5x-3)
