Math Problem Statement

Consider that g is the function whose graph is shown below. Three limits are presented to be evaluated, based on the function's graph at specific points.

Solution

Let's analyze the problem step by step. From the image, we have the graph of the function g(x)g(x), and we are given three limits to solve.

First limit:

limx12+g(x)x2g(x)+g(2)+g(1)=34\lim_{x \to 1} \frac{\sqrt{2 + g(x)}}{x^2 g(x) + g(2) + g(-1)} = \frac{\sqrt{3}}{4} We need to determine the values of g(x)g(x) at specific points like g(1)g(1), g(2)g(2), and g(1)g(-1) from the graph, and then use this information to verify the equation.

Second limit:

limx1g(x)+1x2g(x)+g(2)+g(1)=13\lim_{x \to 1} \frac{\sqrt{g(x) + 1}}{x^2 g(x) + g(2) + g(-1)} = \frac{1}{3} Again, we will use the values of g(x)g(x) from the graph at x=1x = 1, x=2x = 2, and x=1x = -1, and then substitute them into the equation.

Third limit:

limx1x2g(x)g(2)g(1)5+5g(x)=310\lim_{x \to 1} \frac{x^2 g(x) - g(2) - g(-1)}{5 + 5g(x)} = -\frac{3}{10} The approach here is similar: determine the necessary values from the graph and then substitute them into the equation.

Now, let's gather the information from the graph:

From the graph, we can estimate the following values:

  • g(1)g(1)
  • g(2)g(2)
  • g(1)g(-1)

Once we have these values, we can substitute them into the limit expressions and confirm the given results.

I'll begin by estimating these values from the graph. The points at x=1x = 1, x=2x = 2, and x=1x = -1 correspond to the following values of g(x)g(x):

  • g(1)=1g(1) = 1
  • g(2)=0g(2) = 0
  • g(1)=1g(-1) = -1

Substituting into the first limit:

limx12+g(1)12g(1)+g(2)+g(1)=2+1121+0+(1)=30\lim_{x \to 1} \frac{\sqrt{2 + g(1)}}{1^2 g(1) + g(2) + g(-1)} = \frac{\sqrt{2 + 1}}{1^2 \cdot 1 + 0 + (-1)} = \frac{\sqrt{3}}{0} It seems the denominator becomes 0, so we need to check the behavior of the limit more carefully, as there could be a different result when taking the limit from both sides.
