Which graph is a one-to-one function

Graph of a one-to-one function if f is a one-to-one function then no two points (x1,y1), (x2,y2) have the Same y-value. Therefore horizontal line cuts the graph of the equation y = f (x) more than omce. Horizontal line test: A graph passes the horizontal line test if each horizontal line cuts the graph at almost once.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
