the domain:

the equation:

4 is in the domain
-2 is not in the domain
The answer:

***
Also, the answer in 13 is {8}. -3 is not in the domain. Replace x with -3 and you'll see:

It's not true so -3 isn't a solution to this equation.
Yes because the fractions denominator gets bigger the numerator gets smaller

f(3) = -1
f(-1) = 7
But there is a minus in front of the left most f. That would make it - 7
Venus is a planet, hence is spherical shaped.
