<u>The correct answer is option</u><u> (A) The x axis</u>
<h2>Step-by-step explanation:</h2>
If a function is symmetric with respect to the x-axis, then f (x) = - f (x). The following graph is symmetric with respect to the y-axis (x = 0). Note that if (x, y) is a point on the graph, then (- x, y) is also a point on the graph. As we can see from the attached graph it shows the same phenomenon.
The graph of the equation x=y2+4 is symmetric with respect to the x-axis.
To test for symmetry with respect to the x-axis we substitute -y in place of y and simplify the equation. If the resulting equation is identical to original one then the function is symmetric with respect to the x-axis;
