Answer:
y=-12
Step-by-step explanation:
-2(18-3y)=7y+2y
-36+6y=9y
9y-6y=-36
3y=-36
y=-12
Answer:
Step-by-step explanation:
-14<7x
-14/7<7/7x
2<x

5 + x - 2 = -8
x + 3 = -8
x = -11</span>
A relation is (also) a function if every input x is mapped to a unique output y.
In terms of graphical representation, this implies that a graph represents a function if there doesn't exist a vertical line that intersects the graph more than once. So:
- The first graph is exactly a vertical line, so it's not a function.
- The second graph represents the function y=x, so it's a function: you can see that every possible vertical line crosses the graph only once.
- The third graph is not a function, because you can draw vertical lines that cross the graph twice.
- Similarly, in the fourth graph you can draw vertical lines that cross the graph twice
- The fifth graph is a function, because every vertical line crosses the graph once
- The last graph is a function, although discontinuous, for the same reason.
Answer:
Both of these values don't have asymptotes.
