i do not understand why they graph it with a line and a circle. I know what the circle and the line mean, i just do not understand how they apply to this graph.
Are you talking about the greatest integer function that looks like this?Curd said:i do not understand why they graph it with a line and a circle. I know what the circle and the line mean, i just do not understand how they apply to this graph.
"int(x)" in a graph refers to the integer value of the x coordinate. This means that the x value on the graph is a whole number, and does not have any decimal or fractional components.
The difference between "int(x)" and "x" on a graph is that "x" represents the exact value of the x coordinate, including any decimal or fractional components. "int(x)", on the other hand, represents the integer value of the x coordinate, which is rounded down to the nearest whole number.
"int(x)" is used in some graphs to represent discrete data or to highlight specific points on the graph that have integer coordinates. It can also be used to simplify the graph and make it easier to read by removing unnecessary decimal values.
Yes, "int(x)" can be negative in a graph. This means that the x coordinate is a negative integer, such as -1, -2, -3, etc. It is important to pay attention to the scale of the graph to determine the exact value of the negative integer.
"int(x)" is calculated by rounding down the x coordinate to the nearest integer. This means that if the x coordinate is already a whole number, the "int(x)" value will remain the same. However, if the x coordinate has decimal or fractional components, they will be disregarded and the "int(x)" value will be the integer part of the number.
