What is the domain of the function?

A. is the domain of function.

Step-by-step explanation:

We know that , the domain of definition of a function is the set of "input" or argument values for which the function is defined. The function provides an "output" or value for each member of the domain. Conversely, the set of values the function takes on as output is termed the image of the function, which is sometimes also referred to as the range of the function. Basically , if Y = function of x then, all values of x is domain and all values of y is range !.

In the above question , with the help of graph its clear that value of x can't be less than -2. ∴ is the domain of function.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
