Math Problem Statement

Evaluate the limit lim(x -> -1) (2x^3 - 4x^2 + 1)

Solution

The image shows a limit evaluation problem:

limx1(2x34x2+1)\lim_{{x \to -1}} \left( 2x^3 - 4x^2 + 1 \right)

The steps written are as follows:

  1. Substitute x=1x = -1 directly into the expression: 2(1)34(1)2+12(-1)^3 - 4(-1)^2 + 1

  2. Simplify the terms: 2(1)4(1)+12(-1) - 4(1) + 1

    Which results in: 24+1-2 - 4 + 1

  3. Finally: 24+1=5-2 - 4 + 1 = -5

Thus, the evaluated limit is: 5\boxed{-5}

Let me know if you need further details or clarification!

Here are 5 relative questions to expand on this:

  1. How do you find the limit when direct substitution results in an indeterminate form like 00\frac{0}{0}?
  2. What is the difference between one-sided and two-sided limits?
  3. How can L'Hôpital's Rule be used to solve limits involving indeterminate forms?
  4. What are the steps to apply the Squeeze Theorem for finding limits?
  5. How can limits be used to find the derivative of a function?

Tip: Always check if direct substitution gives a real value before attempting more complex methods like factoring or L'Hôpital's Rule for evaluating limits.
