(See Steps) If f(x)=x^2 / 3(2 x-5), then f^prime(x)=(10)/(3) ((x-1))/(x^1 / 3), and f^prime \prime(x)=(10)/(9) ((2 x+1))/(x^4 / 3), solve the following.
Question: If \(f(x)=x^{2 / 3}(2 x-5)\), then \(f^{\prime}(x)=\frac{10}{3} \frac{(x-1)}{x^{1 / 3}}\), and \(f^{\prime \prime}(x)=\frac{10}{9} \frac{(2 x+1)}{x^{4 / 3}}\), solve the following.
- Find the domain of \(f\). (1 point)
- Find the \(x\) -and \(y\) -intercepts. (3 points)
- Find the critical numbers of \(f\). ( 2 points)
- Find the intervals where \(f\) is increasing and the intervals where \(f\) is decreasing. (4 points)
