The set of all possible values which qualify as inputs to a function is known as the domain of the function or It can also be defined as the entire set of values possible for independent variables.
- Domain can be found if – the denominator of the fraction is not equal to zero and the digit under the square root bracket is positive. (In case of a function with fraction values).

For e.g. the domain of the function F is set A i.e. {India, Pakistan, Australia, Sri Lanka}.

To find the domain we need to look at the values of the independent variables which are allowed to use as explained above i.e no zero at the bottom of fraction and no negative sign in square bracket.

Directrix : x + 5 = 0 Latus Rectum ; 20 Step-by-step explanation: Hi, Given equation of circle is x² + y² - 10x + 9 = 0 Center of circle = (-1/2*coefficient of x, -1/2*coefficient of y) Center of the above circle is ( 5, 0). For the given parabola, Vertex is at Origin O (0, 0) Focus is at the center of the circle , S ( 5, 0) Axis of the parabola is the line joining the vertex and focus of parabola, Since both the vertex and focus have their y-coordinate as 0 Equation of Axis is x-axis which is y = 0. Distance between the Vertex and Focus is 'a' which is 1/4 th of Latus Rectum ⇒1/4 * Latus Rectum = 5 ⇒ Latus Rectum = 20. Directrix is the line perpendicular to the axis and passing through the point Z on the axis such that midpoint of SZ is the vertex of the parabola. Hence , coordinates of Z will be ( -5, 0). Any equal perpendicular to x-axis will be of the form x = k , but this passes through Z( -5, 0),hence Equation of directrix is x = -5.
