Def of function in math
WebInvertible functions and their graphs. Consider the graph of the function y=x^2 y = x2. We know that a function is invertible if each input has a unique output. Or in other words, if each output is paired with exactly one input. But this is not the case for y=x^2 y = x2. Take the output 4 4, for example. WebDomain of a Function. more ...
