To solve these problems, we need to find the product of the given functions for each question.**First Question:**Given:- \( f(x) = -4x \)- \( g(x) = x^2 - 4 \)We need to find \( f(x) \cdot g(x) \).Calculate:
Distribute
across the terms in \(g(x)\):
The correct answer is:-
**Second Question:**Given:- \( g(x) = 4x - 1 \)- \( f(x) = 3x - 3 \)We need to find \((f \cdot g)(x)\).Calculate:
Use the distributive property (FOIL method):
The correct answer is:-
