Question

guided practice
let ( f(x) = 9x - 1 ) and ( g(x) = x^3 ).
evaluate ( (g circ f)(1) ).
a. 512
b. 1
c. 26
d. 8

Explanation:

Step1: Calcular \( f(1) \)

Para \( f(x) = 9x - 1 \), sustituimos \( x = 1 \):
\( f(1) = 9(1) - 1 = 9 - 1 = 8 \).

Step2: Calcular \( g(f(1)) \)

Como \( f(1) = 8 \), y \( g(x) = x^3 \), sustituimos \( x = 8 \):
\( g(8) = 8^3 = 512 \).

Answer:

A. 512
