In the mathematics concept, a polynomial function is an expression of finite measurement, lengthwise it is constructed from variables and constant values, using only the operations of addition, subtraction, multiplication, and non-negative, whole-number exponent values. For example, 3x2 − 5x + 9 is a polynomial, but 3/x2 − 5/x + 9x3/2 is not, because its second term involves division by the variable x and because its third term contains an exponent that is not a whole number. In this article we shall discuss about function of x graph.
Sample Problem for Function of X Graph:
Problem 1:
Solve the function f(x) = 2 x + 3.find the coordinate of vertex of the triangle formed by lines and the x axis in graphing polynomial.
Solution:
F(x) = 2x + 3
We take f(x) = -y
We get, 2 x – y + 3 = 0
Thus, 2x – y = -3
2x = y – 3
Equation (1) is divided by -1. We get
-2x = -y + 3
y = 2x + 3 -------------- (1)
From equation (1) we get the following values
X -2 -1 0 1
Y -1 1 3 5
Problem 2:
Solution:
Given:
F(x) = -x + 4
We take f(x) = y
We get, -x + y + 4 = 0
Thus, -x + y = -4
-x = -y – 4
y = x - 4
From equation (1) we get the following values
X 0 1 2 3
Y -4 -3 -2 -1
Function of X Graph:problem 3:
Solve the function f(x) = -2 x - 3.find the coordinate of vertex of the triangle formed by lines and the x axis in graphing polynomial.Solution:
Given:
F(x) = -2x - 3
We take f(x) = -y
We get, -2 x - y - 3 = 0
Thus, -2x - y = 3
-2x = y + 3
Equation (1) is divided by -1. We get
2x = -y -3
y = -2x - 3 -------------- (1)
From equation (1) we get the following values
X -2 -1 0 1
Y 1 -1 -3 -5
