I think your question seems to be :-
Write the equation of the circle that has a center of (-7, 17) with a radius of √19
So , as we know that the equation of circle with centre at <em>(h,k)</em> and <em>radius r</em> is given by . Now , using same concept in this question ;
<em>This is the required equation of Circle </em>
A function is positive if it lies above the x axis.
This function is positive before x = -4, i.e. over the interval
It is negative elsewhere, i.e. over the interval
So, the only correct option is the second one.
