Answer
Explanation:
Step1: Find the domain
For (y = \ln(3 - 5x^{2})), the argument of the logarithm must be positive. So (3-5x^{2}>0), which gives (x^{2}<\frac{3}{5}) or (x\in(-\sqrt{\frac{3}{5}},\sqrt{\frac{3}{5}})).
Step2: Find the first - derivative
Using the chain rule, if (y=\ln(u)) and (u = 3-5x^{2}), then (y^\prime=\frac{u^\prime}{u}). Since (u^\prime=-10x), (y^\prime=\frac{-10x}{3 - 5x^{2}}).
Step3: Find the second - derivative
Using the quotient rule ((\frac{f}{g})^\prime=\frac{f^\prime g - fg^\prime}{g^{2}}), where (f=-10x) and (g = 3-5x^{2}). Then (f^\prime=-10) and (g^\prime=-10x). [ \begin{align*} y^{\prime\prime}&=\frac{-10(3 - 5x^{2})-(-10x)(-10x)}{(3 - 5x^{2})^{2}}\ &=\frac{-30 + 50x^{2}-100x^{2}}{(3 - 5x^{2})^{2}}\ &=\frac{-30 - 50x^{2}}{(3 - 5x^{2})^{2}}\ &=\frac{-10(3 + 5x^{2})}{(3 - 5x^{2})^{2}} \end{align*} ]
Step4: Analyze the second - derivative for inflection points
Set (y^{\prime\prime}=0). The numerator (-10(3 + 5x^{2}) = 0) has no real solutions because (3+5x^{2}>0) for all real (x).
Answer:
B. There are no inflection points.
