Let f(x)=y
f^-1(x)=x
y=1/(x+5) - 1
y+1=1/(x+5)
(x+5)=1/(y+1)
x=1/(y+1)-5
f^-1(x)=1/(x+1) -5
denominator cannot equals to zero
x+1≠0
x≠-1
answer
B
Answer:
7 sqrt(3) =x
Step-by-step explanation:
We know that sin 60 = opposite / hypotenuse
sin 60 = x/14
Multiply both sides by 14
14 sin 60 = x
14 * (sqrt(3)/2) =x
7 sqrt(3) =x
