Is this function injective?
To determine if a function is injective, we need to check if each input value maps to a unique output value. If the function f(x) = x^2 is defined on the set of real numbers, then it is not injective because multiple input values (e.g. 2 and -2) map to the same output value (4). Therefore, the function f(x) = x^2 is not injective. **
How can one prove that f is injective if g is injective?
One way to prove that function f is injective if function g is injective is to show that for any two distinct inputs x1 and x2, the outputs f(x1) and f(x2) are also distinct. Since g is injective, we know that g(x1) and g(x2) are distinct, and we can use this property to show that f is injective as well. Specifically, we can use the fact that g(f(x1)) = g(f(x2)) implies f(x1) = f(x2), and since g is injective, this implies x1 = x2. Therefore, f is injective. **

How to show that if f and g are injective, then gf is also injective?
To show that if f and g are injective, then gf is also injective, we can use the definition of injective functions. An injective function is one where distinct inputs map to distinct outputs. So, if f and g are injective, then for any distinct inputs x1 and x2, f(x1) ≠ f(x2) and g(y1) ≠ g(y2) for any distinct outputs y1 and y2. Now, consider the composition gf. If gf(x1) = gf(x2), then f(x1) = f(x2), which implies x1 = x2 by the injectivity of f. Therefore, gf is also injective. **

Are these mappings injective or surjective?
The first mapping is injective because each element in the domain is mapped to a unique element in the codomain. The second mapping is surjective because every element in the codomain is mapped to by at least one element in the domain. **
-
Are these mappings injective and surjective?
The first mapping is not injective because multiple elements in the domain map to the same element in the codomain. However, it is surjective because every element in the codomain is mapped to by an element in the domain. The second mapping is injective because each element in the domain maps to a unique element in the codomain. However, it is not surjective because not every element in the codomain is mapped to by an element in the domain. **

Is the function injective or surjective?
To determine if a function is injective or surjective, we need to look at its properties. A function is injective if each element in the domain maps to a unique element in the codomain, meaning no two different elements in the domain map to the same element in the codomain. A function is surjective if every element in the codomain is mapped to by at least one element in the domain. To determine if a function is injective or surjective, we can analyze its graph, its algebraic representation, or its properties. If the function passes the horizontal line test, it is injective. If every element in the codomain has at least one pre-image in the domain, the function is surjective. If the function is both injective and surjective, it is bijective. **
How can one show that if f and g are injective, then gf is also injective?
To show that if f and g are injective, then gf is also injective, we need to prove that for any two distinct elements a and b in the domain of gf, their images under gf are also distinct. Since f and g are injective, we know that f(a) ≠ f(b) and g(f(a)) ≠ g(f(b)). Therefore, it follows that gf(a) ≠ gf(b), proving that gf is injective. **
