Question 7 • CMS 2026-2027 NC Math 1 CREDIT RECOVERY

Study these equations: f of x is equal to 2 x minus 4 g of x is equal to 3 x plus 1 What is h of x is equal to f x g x ?

Answer
A
h of x is equal to 6 x squared plus 2 x minus 4
B
h of x is equal to 6 x squared minus 10 x minus 4
C
h of x is equal to 6 x squared minus 12 x minus 4
D
h of x is equal to 6 x squared plus 14 x plus 4

Explanation

Since h(x) = f(x)g(x), multiply the two expressions: (2x − 4)(3x + 1). Distributing gives 6x² + 2x − 12x − 4, which simplifies to 6x² − 10x − 4. Therefore, the correct choice is C, h(x) = 6x² − 10x − 4.
