Yes.
a test for a function is the vertical line test, so think about drawing a vertical line on top of this picture. if at any point the line is touching the graph more than once, it is not a function. this graph passes the vertical line test

It is a function because there is only one y intersection per one unique x intersection

Talia used 1/3 of a piece of wood for the base of her project 1/4 of the piece of wood for the vertical support and the rest for

Answer:

The fraction of wood used for horizontal support is $\frac{5}{12}$ .

Step-by-step explanation:

Assume that the total piece of wood is of length 1.

It is provided that Talia used $\frac{1}{3}$ of the piece of wood for the base of he project.

She use $\frac{1}{4}$ of the piece of wood for the for the vertical support.

The remaining wood she used for horizontal support.

The amount of wood used for horizontal support can be computed by the subtracting the amount of wood used for base of the project and vertical support form 1.

Compute the amount of wood used for horizontal support as follows:

$Horizontal\ support=1-Base\ of\ project-Vertical\ support\\= 1 - \frac{1}{3}-\frac{1}{4}\\ =\frac{12-4-3}{12} \\=\frac{5}{12}$
