WebThe probability mass function, P ( X = x) = f ( x), of a discrete random variable X is a function that satisfies the following properties: P ( X = x) = f ( x) > 0, if x ∈ the support S. ∑ x ∈ S f ( x) = 1. P ( X ∈ A) = ∑ x ∈ A f ( x) First item basically says that, for every element x in the support S, all of the probabilities must ...

WebJul 18, 2024 · Example 4.7.1. Find the domain and range of the following function: f(x) = 5x + 3. Solution. Any real number, negative, positive or zero can be replaced with x in the given function. Therefore, the domain of the function f(x) = 5x + 3 is all real numbers, or as written in interval notation, is: D: ( − ∞, ∞). Because the function f(x) = 5x ... WebJul 18, 2024 · Example 4.7.1.

WebJun 7, 2024 · Use the antiderivatives to obtain the exact equations for f'(x) and f(x). From that we get: f'(x)= 2x^2 + 4x + 3 and f(1)=16/3 We can apply the antiderivative to: … WebEDIT: For fun, let's see if the function in 1) is onto. If so, then for every m ∈ N, there is n so that 4 n + 1 = m. For basically the same reasons as in part 2), you can argue that this function is not onto.
