WebFor instance, the function f(x) = x^2 is not one to one, because x = -1 and x = 1 both yield y = 1. If you look at the graph of your function, f(x) = -2x + 4, you'll notice the graph of a function is linear. These functions are one to one by default. Another way to see if a function is one to one is the evaluate and see if f(m) = f(n) leads to ... Webdetermine whether a linear transformation is one-to-one, onto, both, or neither. Theorem 2. A linear transformation T: Rn!Rm is one-to-one if and only if the equation T(x) = 0 has only the trivial solution. Theorem 3. Let T: Rn!Rm be a linear transformation, and let A2Rm n be its standard matrix. Then 1.
