#### Answer

$a)x=-1,x=1$
$b)y=1$

#### Work Step by Step

The x-intercept is the point at which the graph of the function crosses the x-axis, so we can use this information to find the answer to the first question. However, in this problem there are two crossing points, so from left to right there are two points that are both included in the answer.
The y-intercept is the point at which the graph of the function crosses the y-axis, and we can use this to determine the answer to the second question.
