Answer:

x≠-1,1

Step-by-step explanation:

f(g(x)) is a composition where g(x) is is substituted for x in f(x).

Recall, f(x) is 2/x. So we write 2/|x|-1. This places x in the denominator and 0 cannot be in the denominator x. Any value of x that makes the denominator 0 will not be in the domain.

|x|-1=0

|x|=1

x=1,-1

Answer question 4 please?
Grace [21]

Answer:

8

Step-by-step explanation:

Sides AB and AC are equal

So,

3x - 5 = 7

+ 5 on both sides

3x = 12

divide both sides by 3

x = 4

Now take the 2x and plug in x for 4.

2(4) = 8

Final answer is 8.
