Answer 1

true or false

Answer 2

Do you know the definition of a function?

Answer 3

A function is a special relationship where each input has a single output.

Answer 4

Yes. a parabola is a function because when you draw a vertical line on it, it wouldn't pass through 2 points.

Answer 5

thanks

Answer 6

is this a function

Answer 7

Try doing the vertical line test? Would this be considered a function? does it pass the test?

Answer 8

false. the vertical line test disproves that statement. If an equation is a function, a vertical line should be able to pass through any x value and only intersect the graph of the function once. This is not true for polar functions.
