$(-1, \infty)$

#### Work Step by Step

For interval notation, start with $-1$ and go to infinity, which is greater than that, for what values $x$ can be:$$-1,\infty$$Then add a paren on each side for $x$ not being equal to the value at that extreme:$$(-1,\infty)$$To graph, start with an open point at $-1$ to show that $x$ is not equal to $-1$, then shade towards positive infinity with an arrow on the end to show that $x$ can be any value along that axis.
