f(x) = constant is a function.

Question

True
False

Answer 1

True.

A function \( f(x) = \text{constant} \) is indeed a function because it assigns a single output (the constant value) to every input \( x \) in its domain. For example, if \( f(x) = 5 \), then for every value of \( x \), \( f(x) \) will always be 5. Hence, the statement is true.
