Question
![**Determine the intervals on which the function is concave up or down and find the points of inflection.**
\( y = 5x^2 + \ln(x) \quad (x > 0) \)
Provide intervals in the form \((\ast , \ast )\). Use the symbol \(\infty\) for infinity, \(\cup\) for combining intervals, and an appropriate type of parenthesis "(", ")", "[", or "]", depending on whether the interval is open or closed. Enter \(\varnothing\) if the interval is empty.
Provide points of inflection as a comma-separated list of \((x, y)\) ordered pairs. If the function does not have any inflection points, enter DNE.
Use exact values for all responses.
