Math Problem Statement

Nos dan las gráficas de f y g. Úselas para evaluar cada límite si existe. Si el límite no existe, explique por qué. (a) lim(x→2) [f(x) + g(x)] (b) lim(x→1) [f(x) + g(x)]

Solution

The image contains two limit problems regarding the functions f(x)f(x) and g(x)g(x), and we are tasked with evaluating these limits based on the graphs of these functions.

The problems are:

  1. limx2[f(x)+g(x)]\lim_{x \to 2} [f(x) + g(x)]
  2. limx1[f(x)+g(x)]\lim_{x \to 1} [f(x) + g(x)]

Explanation of how to approach these problems:

  1. Interpretation of the given limits:

    • For both (a) and (b), the task is to find the sum of the limits of the functions f(x)f(x) and g(x)g(x) as xx approaches a certain value (2 in part (a) and 1 in part (b)).
    • Using the property of limits, limxa[f(x)+g(x)]=limxaf(x)+limxag(x)\lim_{x \to a} [f(x) + g(x)] = \lim_{x \to a} f(x) + \lim_{x \to a} g(x), assuming the individual limits exist.
  2. Analyzing each limit:

    • For part (a), we need to find: limx2f(x)+limx2g(x)\lim_{x \to 2} f(x) + \lim_{x \to 2} g(x)
    • For part (b), we need to find: limx1f(x)+limx1g(x)\lim_{x \to 1} f(x) + \lim_{x \to 1} g(x)

Steps to solve:

  • First, evaluate the individual limits limxaf(x)\lim_{x \to a} f(x) and limxag(x)\lim_{x \to a} g(x) for both a=2a = 2 and a=1a = 1, by looking at the graphs of f(x)f(x) and g(x)g(x) (which were provided but are not visible in the image you uploaded).
  • Once you find these individual limits, simply add them to get the required limits for each case.
