Question

What is a constant?
A.A symbol having a fixed numerical value
B.A variable that takes a fixed value
C.A symbol that can takes different values
D.Can’t be determined

Answer 1

Hint: In this question, we need to comment on the term “Constant”. For this, we will go through all the given four options to check which option suits the given question.

Complete step-by-step answer:
A constant term is a term in an algebraic expression that has constant value and its value cannot be changed or modified by any programming.
In an algebraic equation, y and x are the variables, ‘a’ is the coefficient of the variable x and b is the constant and its value cannot be changed since it is not dependent on any variables of the equation.
Now since a constant is fixed numerical value and its value cannot be changed hence we can say a constant is a symbol having a fixed numerical value.
So, the correct answer is “Option A”.

Note: Constant contains fixed values. It is not changing and not varying terms and has no unit or dimension to them. A constant is represented by the symbols and it generally represented by the same symbol everywhere. Students must note that constant is generally used for defining values that are used many times within a function or the equations.
