- Which functions have the same axis of symmetry?
Ay=(x - 1)^2: y = x2 - 2x-3
B y = (x2)^2: y = x-2x-3
Cy=(x - 1)^22 + 2; y = x^2 – X-3
D y = x² + 2x+3; y = x° -2x-3

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

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.

he has now walked a total of what?

if i know what this is maybe i can
