Question

The graph of f(x) = StartRoot x EndRoot is reflected across the y-axis to create the graph of function g. How do the domains of f and g compare?The domains of f and g are both x ≥ 0.The domains of f and g are both all real numbers.The domain of f is x ≥ 0, while the domain of g is x ≤ 0.The domain of f is x ≤ 0, while the domain of g is x ≥ 0.

Answer 1

The third one

Explanation:

Answer 2

Explanation:

Given that f(x) is reflected across the y-axis to create the graph of function g.

i.e. f is reflected on the line x=0

Hence x will become -x in g.

When domain of f is x>=0 the domain of g can only be x less than or equal to 0.

Hence answer is option 3,The domain of f is x ≥ 0, while the domain of g is x ≤ 0
