Answer

$[-5, \infty)$
1475541289

Work Step by Step

For interval notation, write the range, which is: $$-5,\infty$$Then add a bracket for the left side since it is greater than *or equal to* 5 and a paren for the infinity side because infinity is not a number and therefore cannot be included with a bracket:$$[-5,\infty)$$ To graph, start with a filled in dot at -5, and then shade towards the right (positive infinity) with an arrow to indicate that it goes to infinity.
