Using the graph below, select all statements that are true.

Correct choices: B, C, D

First answer is wrong: a one to one function maps different inputs to different outputs, while you can see that all numbers in are mapped to the same value , for every . So, the function is not one to one.

The second is true: by definition, for all real numbers, x, the greatest integer function returns the largest integer less than or equal to x. This is exactly what is happened with the graph.

The third is true: the greatest integer less than 0.6 is 0.

The fourth is true for the same reason: greatest integer less than 5.1 is 5.

The fifth is false: -3 is actually greater than -3.2, so we have

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.
