Answer
$(1,\infty)$
Work Step by Step
Refer to the graph below.
The graph shows that the function is greater than zero in the interval $|(1,\infty)$ because the graph of the function is above the x-axis ($y=0$), which means that the value of the function is greater than zero on this interval.
$1$ and $-3$ are not included because the inequality involves strictly greater than.
