I will downvote for sure if answered wrong.I need answer as soon as possible. All information is given in the question and If u dont know the complete answer Then dont try to attempt it. I will downvote if you provide wrong answer

For example, the formula for the area of a circle, A = -2, gives the dependent variable A (the area) as a function of the independent variabler (the radius). Functions involving more than two variables also are common in mathematics, as can be seen in the formula for the area of a triangle, A=bb/2. which defines A as a function of both b (base) and h (height). In these examples, physical constraints force the independent variables to be positive numbers. When the independent variables are also allowed to take on negative values-thus, any real number-the functions are known as real-valued function. formula for the area of a circle is an example of a polynomial function. The general form for such functions isPIX) - a0.alx+ a2x2+---+ anx.where the coefficients (ao, a1, a2,,an) are given, x can be any real number, and all the powers of x are counting numbers (1, 2, 3...). (When the powers of x can be any real number, the result is known as an algebraic function.) Polynomial functions have been studied since the earliest times because of their versatility-practically any relationship involving real numbers can be closely approximated by a polynomial function. Polynomial functions are characterized by the highest power of the independent variable. Special names are commonly used for such powers from one to live-linear, quadratic, cubic, quartic, and guintic. Polynomial functions may be given geometric representation. Sid show graph of lupx+2 by means of analytic geometry. The independent variable x is plotted along the x-exis (a horizontal line), and the dependent variable y is plotted along the y-axis (a vertical line). The graph of the function then consists of the points with coordinates (x, yl where y = f[x).
