Math Problem Statement

Let

f(x)=(5x-6)/((2x-3)(4x-1))

Find the domain in interval notation

Note: Use -oo for -∞

, oo for ∞

, U for union.

Solution

To find the domain of the function

f(x)=5x6(2x3)(4x1)f(x) = \frac{5x - 6}{(2x - 3)(4x - 1)}

we need to determine the values of xx that make the function undefined. This will occur when the denominator is zero.

  1. Set the denominator equal to zero: (2x3)(4x1)=0(2x - 3)(4x - 1) = 0

  2. Solve each factor for xx:

    • For 2x3=02x - 3 = 0: x=32x = \frac{3}{2}
    • For 4x1=04x - 1 = 0: x=14x = \frac{1}{4}

The function is undefined at x=32x = \frac{3}{2} and x=14x = \frac{1}{4}.

  1. Exclude these values from the domain. In interval notation, the domain is: (,14)(14,32)(32,)(-\infty, \frac{1}{4}) \cup \left( \frac{1}{4}, \frac{3}{2} \right) \cup \left( \frac{3}{2}, \infty \right)

Final Answer:

The domain of f(x)f(x) in interval notation is: (,14)(14,32)(32,)(-\infty, \frac{1}{4}) \cup \left( \frac{1}{4}, \frac{3}{2} \right) \cup \left( \frac{3}{2}, \infty \right)
