Math Problem Statement

Write in quadratic factored form

Write in quadratic factored form based on the given table of values.

Solution

To write the quadratic equation in factored form based on the given table of values, I will analyze the data provided:

From the table, the function f(x)f(x) appears to depend quadratically on xx. A quadratic equation in factored form is typically written as:

f(x)=a(xp)(xq)f(x) = a(x - p)(x - q)

Key Observations

  • The values of f(x)f(x) are zero when x=6x = 6 and x=8x = 8. These are the roots of the quadratic equation, so the equation can be written as:

f(x)=a(x6)(x8)f(x) = a(x - 6)(x - 8)

Determine the Coefficient aa

To find aa, substitute another point from the table into the equation. For example, use the point (x,f(x))=(2,48)(x, f(x)) = (2, 48):

48=a(26)(28)48 = a(2 - 6)(2 - 8)

Simplify:

48=a(4)(6)48 = a(-4)(-6)

48=24a48 = 24a

a=2a = 2

Final Equation

The quadratic equation in factored form is:

f(x)=2(x6)(x8)f(x) = 2(x - 6)(x - 8)

Would you like a graph of the function or further steps explained?


Here are 5 related questions for deeper exploration:

  1. How would the equation look in standard form after expanding the factors?
  2. Can you find the vertex of this quadratic equation?
  3. How do changes to the coefficient aa affect the shape of the parabola?
  4. What are the domain and range of f(x)f(x) based on the table values?
  5. Can you identify the symmetry in the function from its equation?

Tip: Always verify your derived equation with additional points from the table to ensure accuracy.
