difference between formulas and functions
Answers
Answer:
A formula is statement written by the user to be calculated.
Step-by-step explanation:
A formula is a mathematical sentence with at least one variable. For example 2 + 4 isn’t a formula (there’s no variable), but 2x + 4 is a formula, because there’s a variable. Formulas are used in math to describe relationships. Variables can be any letter from a to z, but you’ll want to follow some general rules for writing formulae:
Abbreviate variables to one letter
Use small letters a, b, c, … z.
Omit the multiplication sign (unless you’re multiplying two numbers like 2*4)
Put the number first if you’re multiplying a variable by a number.
functions are a specific type of formula with exactly one output (y) for every input (x).
For example, if you put a “2” into the formula y = x2, there’s only one output: 4. That’s a function.
If you put a 2 into the formula x = y2, there are two possibilities for each input (x-value): 8 and -8.
All functions are formulas, but not all formulas are functions.
Formula vs Function in Excel
A “function” in Excel is a predefined formula. All Excel built-in functions are also functions in the traditional sense (i.e. you’ll get one output for every input).
