What Does it Mean for a Function to be 1 to 1? - starpoint
A function is considered 1 to 1 if each value in the domain maps to a unique value in the range. In other words, no two distinct inputs produce the same output. This is represented mathematically as f(x) = y, where f is the function, x is the input, and y is the output. If every x-value corresponds to a different y-value, then the function is injective. For example, the function f(x) = 2x is 1 to 1, but the function f(x) = x^2 is not, since both x = 1 and x = -1 produce the same output, y = 1.
