<h3>Explanation</h3>

Determine Function or Not Function by Graph.

We can simply find if a graph is a function or not by doing the line test.

Line Test on Graph

Draw a vertical line on a graph.
See if a vertical line intercepts one or more points on the graph.

If the line intercepts only one point, that means the graph is a function.

If the line intercepts more than one point, it is not a function but rather a relation.

Example of graphs that are not functions

Circle Graph
Any graphs that have more than one y-value for a single x-value. (Example x = 2 but x has more than one y value which is not a function.)

Example of graphs that are functions

Any graphs that have "function" name. (Ex Linear Function)
Graphs that have one x and one y value.

If you have any questions, you can comment.

Answer:

Vertical Line test

Step-by-step explanation:

If you can put a vertical line anywhere on the graph, and it doesn't touch more than one point, then it's a function. A function means there are no repeated x values.

1. Find Angle A :

$x + 24 = 3x$

$3x - x = 2 4$

$2x = 24$

$x = 12$

Angle A :

$3x$

$3 \times 12$

$36 \degree$

2. Find Angle B :

$10x - 27 = 7x$

$10x - 7x = 27$

$3x = 27$

$x = 9$

Angle B :

$10x - 27$

$(10 \times 9) - 27$

$90 - 27$

$63 \degree$

Find Angle C :

$5x + 1 = 6x - 13$

$6x - 5 x = 1 + 13$

$x = 14$

Angle C :

$5x + 1$

$(5 \times 14) + 1$

$70 + 1$

$71 \degree$

Find Angle D :

$6x + 3 = 4x + 39$

$6x - 4x = 39 - 3$

$2x = 36$

$x = 18$

Angle D :

$4x + 39$

$(4 \times 18) + 39$

$72 + 39$

$111\degree$

And it's given :

36° = Angle A = B

63° = Angle B = A

71° = Angle C = H

111° = Angle D = E

Therefore, the answer will be " BAHE "
