Por determinante:
5...1...1
1...0...1 = 0 --> se o determinante for igual a 0, os pontos estarão alinhados.
3...3...1

calculando: (5 x 0 x 1 + 1 x 1 x 3 + 1 x 3 x 1) - (1 x 0 x 3 + 1 x 1 x 1 + 3 x 1 x 5) =
0 + 3 + 3 - 0 - 1 - 15 =
6 - 1 - 15 =
5 - 15 = - 10 --> como não deu zero, os pontos não estão alinhados.

3.5.3 Test (CST): Functions

Hatshy [7]

Based on the function shown in the image attached below, the range of this function is equal to {-8, -3, 5, 7}.

<h3>What is a range?</h3>

A range can be defined as a set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range is the solution set (output of a function) because it comprises all second elements (y-coordinates) of ordered pairs.

Based on the function (see attachment), we can logically deduce that the range of this function is given by {-8, -3, 5, 7} and they all mapped to the domain.
