![Determine the intervals on which the function is concave up or down and find the points of inflection.
y = 19x2 + In(x)
(x > 0)
Provide intervals in the form (*, *). Use the symbol ∞ for infinity, U for combining intervals, and an appropriate type of
parenthesis "(", ")", "[", or "]", depending on whether the interval is open or closed. Enter Ø 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.
