Can some help me solve this.

The fourth (last) function is the correct one.

Step-by-step explanation:

Look at the parent function y = √x,  Its graph goes through (0, 0).  On the other hand, if y = √(x - h), the graph goes through (h, 0) if h is positive, and the graph is translated h units to the right from the graph of y = √x.  If h is negative, the graph is translated h units to the left.

In the four possible answers given, the values of h are {-4, 9, 5, -9}, in that order.  h = -9 results in the graph that is positioned 9 units to the left of the graph of y = √x.  This graph is furthest to the left.  Thus the fourth choice is the correct one.

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.
