Math Problem Statement

find the vertical asymptote of y= 2e^(2x) + e^(-2x) / 2e^(2x) - 3e^(-2x)

Solution

To find the vertical asymptotes of the function

y=2e2x+e2x2e2x3e2x,y = \frac{2e^{2x} + e^{-2x}}{2e^{2x} - 3e^{-2x}},

we need to identify the values of xx that make the denominator zero, since vertical asymptotes occur where the function approaches infinity.

Step 1: Set the Denominator to Zero

Set the denominator equal to zero:

2e2x3e2x=0.2e^{2x} - 3e^{-2x} = 0.

Step 2: Clear the Exponential

To solve for xx, multiply both sides by e2xe^{2x} (which is always positive):

2e4x3=0.2e^{4x} - 3 = 0.

Step 3: Solve for e4xe^{4x}

Rearranging gives:

2e4x=3,2e^{4x} = 3,

which simplifies to:

e4x=32.e^{4x} = \frac{3}{2}.

Step 4: Take the Natural Logarithm

Taking the natural logarithm of both sides:

4x=ln(32).4x = \ln\left(\frac{3}{2}\right).

Step 5: Solve for xx

Finally, divide by 4:

x=14ln(32).x = \frac{1}{4} \ln\left(\frac{3}{2}\right).

Conclusion

The vertical asymptote of the function occurs at:

x=14ln(32).x = \frac{1}{4} \ln\left(\frac{3}{2}\right).

Tip: When analyzing rational functions, always check both the numerator and the denominator for potential zeros and points of discontinuity.
