Question

For f(x)=sqrt x-1 and g(x)=1/x-2
find the domain of fg

Answer 1

\[x>1,x \neq2, x \epsilon R\]

Answer 2

assuming (x-1) and 1/(x-2)

Answer 3

what does the xeR mean?

Answer 4

x is an element of Real numbers ... the epsilon means "is an element of"

Answer 5

are u ok with this answer?

Answer 6

fg =\[\sqrt{x-1}/(x-2)\] so x -1> 0
but x \[\neq 2\]

Answer 7

srry x can equal 1 so w\[x \ge 1, x \neq 2\]e have

Answer 8

made a slip there
