Question

1. which of the following is a constant in the expression $7x^{3}+2$?

a. 2
b. 7
c. $7x^{3}$
d. $x^{3}$

Explanation:

A constant is a value that does not change, regardless of the variable (here, \(x\)). In the expression \(7x^3 + 2\), 2 has no variable attached and is fixed, so it is the constant. 7 is a coefficient, \(7x^3\) is a term with a variable, and \(x^3\) is a variable term. Thus, the constant is 2.

Answer:

a. 2
