In a one-to-one function, given any y there is only one x that can be paired with the given y. A graph of a function can also be used to determine whether a function is one-to-one using the horizontal line test: If each horizontal line crosses the graph of a function at no...
onto 是漫射 台版翻译叫映成函数 映成函数(onto function)：设f：A→B，如果f(A)=B，则f是映成函数。换言之，B理的每一分子都出现作A的像，那f是映成函数。

Functions can map elements from the domain to the codomain in many ways. A function may "hit" every element in the codomain, or it may "miss" some. It may assign more than one x to a y or it may assign exactly one x to each y. We will understand our function better if we know...
Write an informal definition of a one-to-one function. Which of the functions corresponds to the graph?A. f(x) = 2sin x +1 B. f(x) = 2cos x +1 C. f(x) = 2-cos x D. f(x) = sin(2x) +1 Which of the functions corresponds to the graph?A. f(x) = 2e^{-x} ...

What does the word function stand for? By the word function, we understand the responsibility or role one has to play. What is the function of the leaves of plants - to prepare food for the plant and store them? Let us now learn about some types of funct
Show that a one-one function f : \{1, 2, 3 \} \to \{1, 2, 3 \} must be onto. Show that the function f(t) = 5 e^{3t} satisfies y" - 2y'-3y = 0 ; \quad y(0) = 5 Show that the function f(t) = 5e^{2t} satisfies y'' - 3y' + ...

To solve the question, we need to provide examples of functions based on the specified properties: one-one (injective), onto (surjective), or neither. Let's break it down step by step.Step 1: Function that is One-One but Not Onto</stron
