Question

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.

Answer 1

9514 1404 393

Answer:

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

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"
