Answer:
The graph is not a function of x because x=0 intersects the graph at two points.
Step-by-step explanation:
The vertical line test is when you draw, well, a vertical line through the graph. the slope of a vertical line is undefined, and the formula written as x=_. So we can eliminate the choices with y=_.
We can clearly see that this graph isn't a function, so we can eliminate the answer choices that say that the graph is a function.
Just in case, draw a line at x=0, to check that it does indeed cross the graph in 2 places.

Answer:
a=8
Step-by-step explanation:
-5(a+3)=-55
So we multiply -5 times a and 3 so we get:
-5a-15=-55
+15 +15
____________-
-5a=-40
÷-5 ÷-5
____________
a=8
Hope this helped :D
