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 (-\sqrt{\frac{3}{5}}<x<\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}). (u^\prime=-10x), so (y^\prime=\frac{-10x}{3 - 5x^{2}}). Set (y^\prime = 0), then (-10x=0), which gives (x = 0).
Step3: Analyze the sign of the first - derivative
When (x\in(-\sqrt{\frac{3}{5}},0)), (y^\prime>0) (function is increasing). When (x\in(0,\sqrt{\frac{3}{5}})), (y^\prime<0) (function is decreasing). So (x = 0) is a local maximum. (f(0)=\ln(3)).
Step4: Check for local minima
Since the function is increasing on ((-\sqrt{\frac{3}{5}},0)) and decreasing on ((0,\sqrt{\frac{3}{5}})), there are no local minima.
Step5: Check for absolute maxima
Since the function has only one critical point (x = 0) in the domain ((-\sqrt{\frac{3}{5}},\sqrt{\frac{3}{5}})) and the function is continuous on the open interval ((-\sqrt{\frac{3}{5}},\sqrt{\frac{3}{5}})), and (\lim_{x\rightarrow\pm\sqrt{\frac{3}{5}}^{-}}\ln(3 - 5x^{2})=-\infty). The absolute maximum occurs at (x = 0) and (f(0)=\ln(3)).
Answer:
For local minimum points: B. There are no local minimum points. For absolute maximum points: A. The absolute maximum point(s) is/are ((0,\ln(3)))
