If the graph of a function passes through the origin, what must be true of the function? A. The graph of the function must be a straight line.
B. The domain of the function contains only positive values of x.
C. The function cannot contain a non-zero constant.
D. As x increases, y must also increase.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

according to egenuity the answer is
