Saying y is a function of x means y is related to x by some formula

True
False

Correct Answer

True

Explanation

In fact, this statement gives some idea about a function, but it is incomplete. In traditional algebra, x and y stand for numbers. But today, functions can be defined that have nothing to do with numbers.  However, the concept of function in calculus is mostly concerned with functions which are related to numbers.
