Math Problem Statement

Укажите точки пересечения функции y = (x^3 - 1) / 4x^2 с осью OX.

Solution

To find the intersection points of the given function y=x314x2y = \frac{x^3 - 1}{4x^2} with the OXOX-axis, we need to solve for where y=0y = 0.


Steps:

  1. Set y=0y = 0: x314x2=0\frac{x^3 - 1}{4x^2} = 0

  2. The numerator must equal zero for the fraction to be zero (since the denominator cannot be zero): x31=0x^3 - 1 = 0

  3. Solve for xx: x3=1    x=1x^3 = 1 \quad \implies \quad x = 1

  4. At x=1x = 1, substitute back into the function to confirm y=0y = 0: y=(1)314(1)2=04=0y = \frac{(1)^3 - 1}{4(1)^2} = \frac{0}{4} = 0

Thus, the intersection point is x=1x = 1 and y=0y = 0.


Final Answer:

10 (written as x=1,y=0x = 1, y = 0).


Do you want further explanation on any step?

Here are related questions to expand understanding:

  1. How do we find the intersection points with the OYOY-axis instead?
  2. What if the denominator also allowed a solution x=0x = 0? (Asymptote discussion)
  3. How does the behavior of x3x^3 and x2x^2 affect the graph near x=0x = 0?
  4. Could this function have vertical asymptotes? If so, where?
  5. How would the graph behave at larger positive or negative values of xx?

Tip: Always ensure the denominator in a rational function is non-zero to avoid undefined points.
