Answer:
The completion of the statement depends on the context and the specific function "f(a)." In mathematics, the statement "f(a) is..." can be completed in various ways depending on the properties or characteristics of the function and its input value "a." Here are a few possible completions:
f(a) is a real number.
f(a) is the value of the function f evaluated at the input a.
f(a) is a solution to a given equation or inequality.
f(a) is a continuous function.
f(a) is differentiable at the point a.
f(a) is an element of a specific set or range.
The appropriate completion will depend on the specific context and properties of the function being discussed.
I will answer in the comments if you provide me witha diagram or something...
