Following are the required information's :-
The vertex is the maximum value
The function is positive for no values of x
The function is decreasing when x > -1
The domain of the function is all real numbers
The range of the function is all numbers less than or equal to 0.
Graphing functions is drawing the curve that represents the characteristic at the coordinate plane. If a curve (graph) represents a function, then each point on the curve satisfies the feature equation. for example, the subsequent graph represents the linear function f(x) = -x+ 2.
Graphs show many input-output pairs in a small area. The visual records they provide often makes relationships less difficult to recognize.
In mathematics, the graph of a function f is the set of ordered pairs, in which {displaystyle f(x)=y.} within the not unusual case where x and f(x) are actual numbers, those pairs are Cartesian coordinates of points in two-dimensional space and for this reason shape a subset of this aircraft
