Question

Dada la siguiente función, calcular. Ayúdame por favor ​

Answer 1

Respuesta:

(f+g)(1) = 4

(fog)(10) = 4

Explicación paso a paso:

• (f+g)(x) = Ιx-5Ι + √(x-1)

(f+g)(1) = Ι1-5Ι + √(1-1)

(f+g)(1) = Ι-4Ι + √0

(f+g)(1) = 4 + 0

(f+g)(1) = 4

• (fog)(x) = [√(x-1)]² - 2.√(x-1) + 1

(fog)(10) = [√(10-1)]² - 2.√(10-1) + 1

(fog)(10) = [√(9)]² - 2.√9 + 1

(fog)(10) = 9 - 2 . 3 + 1

(fog)(10) = 9 - 6 + 1

(fog)(10) = 4
