Math Problem Statement

Find f'(x) for f(x) = ln(2x^2 - 3x + 4).

Solution

To solve for f(x)f'(x) when f(x)=ln(2x23x+4)f(x) = \ln(2x^2 - 3x + 4), we will apply the chain rule.

Solution:

Given: f(x)=ln(2x23x+4)f(x) = \ln(2x^2 - 3x + 4)

Using the derivative formula for ln(u)\ln(u): ddx[ln(u)]=1uu\frac{d}{dx}[\ln(u)] = \frac{1}{u} \cdot u'

Here, u=2x23x+4u = 2x^2 - 3x + 4. Now, we differentiate uu with respect to xx:

u=ddx(2x23x+4)=4x3u' = \frac{d}{dx}(2x^2 - 3x + 4) = 4x - 3

Now, substitute into the derivative formula:

f(x)=12x23x+4(4x3)f'(x) = \frac{1}{2x^2 - 3x + 4} \cdot (4x - 3)

Thus, the derivative is:

f(x)=4x32x23x+4f'(x) = \frac{4x - 3}{2x^2 - 3x + 4}

Tip: When working with logarithmic functions, always verify that the argument of the logarithm is positive to ensure the function is well-defined.
