Function Tables

A function table is a chart that shows how each input value (x) is related to an output value (y) based on a specific function rule.

It represents a linear function where the output (y) is 5 units greater than the input (x).

The output is 10, calculated as $$5 \times 2 = 10$$ .

Substitute the input value into the function rule and solve for the output.

The output is 5, calculated as $$2 \times 2 + 1 = 5$$ .

It means for every unit increase in the input, the output increases by three times that amount.

The output is 20, calculated as $$4 \times 5 = 20$$ .

The relationship is defined by the function rule, which determines how each input is transformed into an output.

A linear function is a function that creates a straight line when graphed, typically in the form $$y = mx + b$$ .

The input is the value that is put into a function to obtain an output.
