Write an equation in function notation for this relation.

Short Answer

Expert verified

The equation in function notation for this relation is $y = 3 x$ .

Step by step solution

Step 1. Find the points from the graph and make the table and find the difference between the values of x and y.

The observed points from the graph are $(鈭� 2, 鈭� 6), (鈭� 1, 鈭� 3), (0, 0), (1, 3), (2, 6)$ and $(3, 9)$ .

Make the table by using the observed points from the graph.

x	$- 2$	$- 1$	0	1	2	3
y	$- 6$	$- 3$	0	3	6	9

Calculate the difference between and.

From the above table it can be noticed that the difference between x is 1 and the difference between the y is 3.

This implies the value of constant of variation (k) is given by:

$k = \frac{3}{1} = 3$

Step 2. Find the equation in function notation for this relation.

As, the value of k is 3. Therefore, the equation in function notation for this relation is given by:

$\begin{matrix} y = k x \\ y = 3 x \end{matrix}$

Therefore, the equation in function notation for this relation is $y = 3 x$ .
