If f(x)=x-3/x and g(x)=5x-4, what is the domain of (f•g)(x)

Step-by-step explanation:

Given functions are,

Now, by the property of composition of functions,

   ( From equation (2) )

  ( From equation (1) )

Which is a rational function,

Since, the rational function is defined for all real numbers except those real values for which denominator = 0,

If 5x - 4 = 0

So, the function (fog) is defined for all real numbers except 4/5,

Therefore, the domain of (fog)(x) is .

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
