Answer:
5) x:-7.5
6) y:7.8
7) a:-11
8) y:1
Step-by-step explanation:
Find the domain and range. Graph the relation and determine whether it is a function or not
1 answer:
The domain is the set of all x-coordinates and
the range is the set of all y-coordinates.
So the domain for this relation is {0, 1, 2, 3, 4}
and the range is {0, -1, -4, -9, -16}.
Now, I graph these points below.
For the relation tobe a function, it must pass the vertical line test.
If we can draw a vertical line that passes through only one point
anywhere on the graph, the relation is a function.
Notice that if you were to draw a vertical line,
no line would intersect two points on the same line.

let's change some the 0.1 to say 1/10, just the fraction version of it.
when checking an absolute value expression, we do the one-sided limits, since an absolute value expression is in effect a piecewise function with ± versions, so for the limit from the left we check the negative version.
