WebA function is like a microwave, you put something in it, and something will come out. So, an input and an output. For example f (x) = x + 1, given x is 7. You would insert 7 into the equation, f (7) = 7 + 1, which is 8. So the input is 7, resulting in an output of 8. Also, the f (x) part does not mean mulitplication, it is a format used for ... WebSep 23, 2024 · For this function, the rule is that we take the input number that x represents, and then multiply it by 2.
