The graph of f(x) = x is reflected across the y-axis to create the graph of function g. How do the domains off and g compare?

A)The domains of fand g are both x 20.

B)The domains off and g are both all real numbers.

C)The domain offis x 20, while the domain of g is xs 0.

D)The domain offis xs 0, while the domain of g is x 20.

9514 1404 393

  B)  The domains off and g are both all real numbers.

Step-by-step explanation:

The domain of any polynomial function is "all real numbers". A reflected polynomial is still a polynomial.

  f and g both have a domain of "all real numbers"

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
