Step-by-step explanation: Here were given 4 relations in the form of graphs and were asked to determine which one represents a function.

In this situation, we would use what is called the vertical line test.

In other words, if we can draw a vertical line that passes through

more than one point on the graph, then the relation is not a function.

Notice that in this problem, every vertical line draw on a

graph passes through more than 1 point except for W.

So W represents a function.

Answer:

1 feet wide

Step-by-step explanation:

We first need to find the area of the floor.

6*5=30

Then we divide the area by the number of kitchen tiles to get the area of each tile.

30/10=3

After this, we set up a L x W = A equation to solve for w.

3*w=3

3w=3

w=1

Eliminate the parameter.

Answer:
y = 24x³ - 1

Explanation:
We have:
x = $\frac{1}{2} t$
This means that:
t = 2x ...............> I

We are also given that:
y = 3t³ - 1 .............> II

Substitute with I in II to eliminate the t as follows:
y = 3t³ - 1
y = 3*(2x)³ - 1
y = 3*8x³ - 1
y = 24x³ - 1
