Identify whether the relations given in the options are functions or not.

Answer:

Graphs 1, 2, and 3 are not functions. Graph 4 is a function.

Step-by-step explanation:

Use the vertical line test.

Imagine a vertical line moving from left to right.

If in any position of the vertical line, it intersects more than one point on the graph, then it is not a function.

In graphs 1 and 2 it is clear that there are many vertical lines than would intersect the graph at more than one point.

In graphs 3, a vertical line would intersect the vertical parts of the graph at more than 1 point, so graph 3 is not a function.

The only function is graph 4.

Answer:

$170$

Step-by-step explanation:

The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.

$wx = 2(42x + 1)$

We can add up that and the other arcs to 360.

$2(42x + 1) + 29x - 1 + 65x + 3$

$84x + 2 + 29x - 1 + 65x + 3 = 360$

$178x + 4 = 360$

$178x = 356$

$x = 2$

Plug in 2 for WX.

$84(2) + 2 = 170$
