Question
Sketch the graph of$$f(x)=\frac{x^3-2}{x^4}$$Indicate the critical points, local and absolute maxima and minima, vertical and horizontal asymptotes, inflection points and regions where the curve is concave upward or downward.
Step 1
The function is \( f(x) = \frac{x^3 - 2}{x^4} \). The denominator \( x^4 \) cannot be zero, so \( x \neq 0 \). Therefore, the domain of \( f(x) \) is all real numbers except \( x = 0 \). Show more…
