Let f (x) = 1/x and g(x) = x² – 3x. what two numbers are not in the domain of fºg?

For this case we have the following equations:

We must find

By definition of composition of functions we have to:

So:

We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.

So, the roots are:

The domain is given by all real numbers except 0 and 3.

x other than 0 and 3

ANSWER

0 and 3

EXPLANATION

The given functions are

and

Factor the numerator:

The function will be undefined if the denominator is zero.

Therefore 0 and not in the domain of the composed function.

3/6   and 9/18

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.
