Sample Algebra Functions

Introduction of sample algebra functions

Algebra is the branch of mathematics deals with finding unknown variable from the given expression with the help of known values. The variable of algebraic are represents alphabetic letters.In algebra the numbers consider as constants, algebraic expression may include  real number, complex number, matrices and polynomials. In algebra several identities need to find the x values by using this we can simply find  the algebraic expression of the particular function. The sample algebra functions may include in the function of f(x), p(x),… to find the x value of the algebra functions.

For example

Sample algebra functions f(x) = 2x2+3x + 4. In this sample algebra function we have  to find the function of f(2).

Sample Algebra Functions Problem

Problems using the square of the sample algebra functions

Problem1:Using  square  problem in sample algebra functions

f(x) = x2 +2x +4 find the f(4).

Solution :

Given the function of f(x) there is x value is given find the sample algebra functions of

f(x) = x2 +2x +4 find the f(4).

The value of x is4 is given

f(4) = 42 + 2*4 + 4

f(4) = 16 + 8 + 4 In this step 4 square is 16 it is calculate and 2*4 is 8 be added

f(4) = 28

Sample algebra functions of f(4) = x2 +2x +4 find the f(4) is 28.

Problem2; Using  square  problem in sample algebra problem

f(x) = x2 + 5x + 5 find the f(5).

Solution :

Given the function of f(x) there is x value is given find the sample algebra functions of

f(x) = x2 + 5x + 5 find the f(5).

The value of x is 5 is given

f(5) = 52 + 5*5 + 5

f(5) = 25 + 25 + 5 In this step 5 square is 25 it is calculate and 5*5 is 25 be added

f(5) = 55

The algebra 2 function of the f(5) = x2 + 5x + 5 find the f(5) is 55.

Having problem with cbse board exam question papers keep reading my upcoming posts, i will try to help you.

Sample Algebra Functions Using the Cubic Equation

Problems 1: using the cubes equation in sample algebra functions:

f(x) = x3 + 2x2 + 2x + 4 find the sample algebra function f(2).

Solution

Given the function of  f(x) there is x value is given find the sample algebra functions

f(x) = x3 +2x2 + 2x + 4 find the f(2).

Here the value of x is given as 2

f(2) = 23 + 2*22 + 2*2 +4

f(2) = 8 + 8 + 4 + 4 In this step 23 is calculated  as 8 and 2 square is 4

f(2) = 24.

The sample algebra functions of the f(x) = x3 +2x2 + 2x + 4 find the f(2) = 24.

Problems 2: using the cubes of the sample algebra functions

f(x) = 2x3 +4x2 + 3x + 4 find the sample algebra functions of f(4).

Solution

Given the function of  f(x) there is x value is given find the sample algebra functions

f(x) = 2x3 + 4x2 + 3x + 4 find the f(4).

Here the value of x is given as 4

f(4) = 2*43 +  4*42 + 3*4 + 4

f(4) = 128 + 64 + 12 + 4 In this step 4 cubes  is calculated  as 64 and multiplied by 2 we get as 128.Then the 4 square is 16 and multiplied by 4 we get 64.

f(4) = 208

Sample algebra functions of the f(x) = 2x3 +4x2 + 3x + 4 find the f(4) = 208.
