Thus generating a table ofvalues of C such as: 4.50,9.00,13.50, and 18.00.Another example, the variable, say x, in the quadratic equation represents a parabola when it "varies" over a given domain. But the variable in the equation 0=x2+2x+1 is "an unknown quantity. It does not vary." Thus, in this case the vari-able has lost its ability to "vary." Yet in both situations they are referred to as a variable, and this duality is embodied in the definition of a variable as "a symbol used to represent one or more numbers." Could the motivation behind this definition be such that we don't have to make the distinction between an "unknown specific quantity" and a "varying" quantity?Does anyone agree that the above argument has been logically developed oris there some flaw in my reasoning? Thank you.a symbol used to represent one or more numbersSee hereAnswer · 4 votesI don't like the word "variable" in math. When we're solving an equation, x is nothing more than the name of a number whose value we do not yet know, x is not in any sense "variable". It's not as if the value of x can change.And if we are defining a function f, we might say something like, if x is a number, then f(x)=x2+7 . Even here x is not "variable". We are just saying that if x is a (specific) number, then f(x) is the number x2+7.Now, in computer programming, you have variables whose value can actually change. That's different.More Feedback 13231 Champion Forest Dr, miles Flashcards. a symbol, usually a letter, that represents one or more numbers. variable expression. an expression consistion of one more .
