Determine interval$($s$)$ on which the function is increasing, interval$($s$)$ on which the function is decreasing, relative extrema, symmetry, and those intercepts that can be obtained conveniently. Then sketch the graph.

$y=1\mathrm{.}1x^4-22x^2$

On which interval$($s$)$ is the function increasing? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A$.$ The function is increasing on the interval$($s$).$

$($Type your answer in interval notation. Use a comma to separate answers as needed.$)$

B$.$ There is no interval on which the function is increasing.
