( f h ) (x)  = 6 x² - 1

Step-by-step explanation:

Step(i):-

Given f(x)   =  3 x - 4

         g (x)  = −x²+2 x−5

        h (x)  = 2 x² + 1

         j (x)    = 6 x + 2 - 8 x

        K (x)   = 3 x² - x + 7

Step(ii):-

( f h ) (x) = f ( h (x)) = f ( 2 x² + 1 )

                            =  3 (2 x² + 1 ) - 4

                            =  3 ((2 x² ) + 3 - 4

                           =   6 x² - 1

Final -

∴ ( f h ) (x)  = 6 x² - 1

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
