I think its either b or c

anonymous · Answer

What is your answer?

anonymous · Answer

it isn't a because a linear function is a straight line

anonymous · Answer

it is one to one because for every x input there is only one y output

anonymous · Answer

This is B. Every x coordinate has one and only y coordinate value to it. :D

anonymous · Answer

so that cancels d

anonymous · Answer

b?

anonymous · Answer

B? Try to draw a horizontal line in the graph and see if it passes two or more points. if it does, then it is not a one-to-one function

anonymous · Answer

how to know if it's a function? draw a vertical line in the graph and see if it only passes one point.

anonymous · Answer

remember that a function can also be one-to-one

anonymous · Answer

and a linear function is just a straight/diagonal line
