The table of value of the function consist of x and y values.
The graph of the function is shown in the image attached.
How to model the function?
The table of value and the graph of the function y = 1/6 x + 3 is calculated by applying the following method as shown below.
The given function;
y = 1/6 x + 3
when x = -18, the value of y is calculated as;
y = 1/6 (-18) + 3
y = -3 + 3
y = 0
when x = 0, the value of y becomes;
y = 1/6 (0) + 3
y = 3
when x = 1, the value of y becomes
y = 1/6 (1) + 3
y = 1/6 + 3
y = 3.167
when x = 2, the value of y becomes
y = 1/6 (2) + 3
y = 1/3 + 3
y = 3.33
when x = 3, the value of y becomes
y = 1/6 (3) + 3
y = 1/2 + 3
y = 3.5
The table of the values is;
x: -18 0 1 2 3
y: 0 3 3.67 3.33 3.5
The graph of the function is shown in the image attached.
