Math Problem Statement

Укажите точки пересечения функции y = (x^2 - 1) / (4x^2) с осью OX.

Solution

This task requires finding the points of intersection of the given function y=x214x2y = \frac{x^2 - 1}{4x^2} with the OXOX-axis (the x-axis).

Step-by-Step Solution:

  1. Intersection with the x-axis: For the function to intersect the x-axis, the yy-value must be 00. Hence, we solve: x214x2=0\frac{x^2 - 1}{4x^2} = 0 A fraction equals 00 if the numerator is 00, provided the denominator is not 00.

  2. Set numerator to 00: x21=0x^2 - 1 = 0 Solving this gives: x2=1    x=±1x^2 = 1 \quad \implies \quad x = \pm 1

  3. Check denominator: The denominator is 4x24x^2. It is 00 when x=0x = 0, but x=0x = 0 does not satisfy the numerator being 00. Therefore, x=0x = 0 is not a solution.

  4. Intersection points: The function intersects the x-axis at x=1x = 1 and x=1x = -1. The corresponding points are: (1,0)and(1,0)(1, 0) \quad \text{and} \quad (-1, 0)

Final Answer:

The points of intersection are: 1,0and1,01,0 \quad \text{and} \quad -1,0
