Let f(x) represent a function.

which descriptions match the given transformations?

drag and drop the answers into the boxes.

f(x)−4

4f(x)

Remember, if f(x) is a function, when you add a constant to the y-values, that is, if is a constant,  , moves the function f(x) up or down depending the sign of .

And, you stretch or compress the function f(x) in the y-direction by multiplying the function by a constant, that is, cf(x), when c is a constant.

Then f(x)-4 is the function f(x) four units up in the direction of the axis y.

And 4f(x) is the function f(x) stretch by a factor of 4.

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.
