Step-by-step explanation:
3) Domain represents the amount of -values in a function. The image shows that the function's arrows point in both directions (right and left), infinitely, so the domain would be
,
, or
(same thing).
4) Range represents the amount of -values in a function. The function goes downward forever (
) by the indication of an arrow and halts just under the y-axis (
). After combining these two inequalities, you see that the range is
or
(same thing).
5) The -intercept is where the function crosses the
-axis. In this function, the
-intercept is
or
(same thing).
