We start with the function given by the logarithmic expression: y=ln(5x2−3x+4) y = \ln(5x^2 - 3x + 4) y=ln(5x2−3x+4)
To find the derivative y′ y' y′, we apply the chain rule. The derivative of ln(u) \ln(u) ln(u) is 1u⋅dudx \frac{1}{u} \cdot \frac{du}{dx} u1⋅dxdu, where u=5x2−3x+4 u = 5x^2 - 3x + 4 u=5x2−3x+4. Thus, we have: y′=15x2−3x+4⋅(10x−3) y' = \frac{1}{5x^2 - 3x + 4} \cdot (10x - 3) y′=5x2−3x+41⋅(10x−3)
Combining the results, we can express the derivative as: y′=10x−35x2−3x+4 y' = \frac{10x - 3}{5x^2 - 3x + 4} y′=5x2−3x+410x−3
The derivative of the function is: y′=10x−35x2−3x+4 \boxed{y' = \frac{10x - 3}{5x^2 - 3x + 4}} y′=5x2−3x+410x−3
