Answer:
A. x <= 2
Step-by-step explanation:
The domain of a real function should be all real numbers. In
f(x) = sqrt(2-x)
we need 2-x to be non-negative, therefore
2-x >= 0
which implies
x <= 2
Commutative property of multiplication. hope this helps!
Reflected would make a mirror image.
X is located at (1 ,-3)
Since it is being reflected across the Y axis, the X value would be the same.
The Y value is 4 units below Y=1 ( the mirror line) so the new Y value would be 4 units above the mirror line ( 4+1 = 5)
This means X' would be at (1.5)
