Algebra function table allows us to find the value of unknown variables in equations. In Algebra to represent the unknown quantity we use variables which is a letter or symbol. The group of Numbers, symbols, real number and Polynomials that express an operation is called algebraic expression.

In an algebraic function table, we keep organized information that helps to understand Algebraic Equations.

In algebra, to find the unknown value of the Functions which is in the form of p(x) = ax2 + bx + c, we need to find the function variable x.

First we construct a table as follows and put the values like a, b, c, etc.

X |
p(x) = ax2 + bx + c |

a |
p(a) = aa2 + ba + c |

b |
p(b) = ab2 + bb + c |

. . . |
. . . |

z |
p(b) = ab2 + bb + c |

To solve for X we use the provided values of y. Consider the equation f(x) = x

^{2}+ 2x + 4 and the number 1, 2, 3 and 7 as x in the function.

Put the value of x into the equation of function f(x) = x

^{2}+ 2x + 4.

According to the equation, square x, add 2*x and 4 we will get f(x) as a result.

X |
p(x) = x^{2} + 2x + 4 |
F(x) |

1 |
P(1) = 1^{2} + 2*1 + 4 |
7 |

2 |
p(b) = 2^{2} + 2*2 + 4 |
12 |

3 |
p(b) = 3^{2} + 2*3 + 4 |
19 |

7 |
p(b) = 7^{2} + 2*7 + 4 |
67 |
