Does x represent the input or the output?
The input.
Does passing the vertical line test mean that the graph is a function? Yes or no?
Yes.
True or false: a linear function is a straight line.
True.
How would I say: f(x)
"F of x"
Does y represent the input or the output?
The output.
I did the vertical line test and one of my vertical lines passed through the graph three times. Is the graph a function?
No, the graph is not a function.
Non-linear.
Can I represent a function as a table?
Yes, you can represent a function as a table.
(x, y)
In a table of x and y values, there are three -2s with three different outputs. Is the table a function?
No, the table is not a function.
True or false: A non-linear function CAN be a straight line.
False.
