Im going to attach a pic so it will be easier :)
Square root is the number that when multiplied when itself give the number you are looking for if that makes any sense.
8 is the square root of 64 because 8x8 = 64
You could say 8r+2 times s +4 or –5x2y4
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
