Which description compares the domains of Function A and Function B correctly?

Function A: f(x)=√(-x)

Function B:

• The domain of Function A is the set of real numbers greater than 0.
The domain of Function B is the set of real numbers less than or equal to 0.

• The domain of both functions is the set of real numbers greater than or equal to 0.

• The domain of both functions is the set of real numbers less than or equal to 0.

• The domain of Function A is the set of real numbers greater than 0.
The domain of Function B is the set of real numbers greater than or equal to 0.

2.

Which comparison is correct for the values of f(x) and g(x) when x=−3?

Function A: f(x)=−x^2+4

Function B:

xg(x)
−5−2
−40
−31
−24

• f(−3)=g(−3)

• f(−3)>g(−3)

• f(−3)

1.

The domain of both functions is the set of real numbers less than or equal to 0.

2.  When x  = -3.....function A  = -5     and Function B  = -2

So    g(-3)  >  f(-3)
