Problem on functions- mathematics course 3 answers:

Example problem1:

To find the function of` f(x) = x^2+2x+3,` when `x=2.`

Solution:

`f(x) = x^2+2x+3`

`f(2) = 2^2+2(2)+3`

`f(2)= 4+4+3`

`f(2)=11`

Answer is `11.`

Example problem2:

To find the function of `f(x) = x^2+2x+3` , when `x=3.`

Solution:

`f(x) = x^2+2x+3`

`f(2) = 3^2+2(3)+3`

`f(2)= 9+6+3`

`f(2)=18`

Answer is `18.`

Example problem3:

To find the function of `f(x) = x^2+2x-3, ` when `x=2.`

Solution:

`f(x) = x^2+2x-3`

`f(2) = 2^2+2(2)-3`

`f(2)= 4+4-3`

`f(2)=5`

Answer is `5.`

Problems- Mathematics course 3 answers:

Example 1:

Simplify `x^2 -29xy - x + 29y. `

Solution:

The terms do not have a common factor. However, we classify that the expressions can be combined as follows:

`X^2 -29xy - x + 29y = (x^2 -29xy) - (x-29y)`

`= x(x -29y) + (-1) (x-29y)`

`= (x -29y) [x + (-1)]`

`= (x -29y) (x - 1).`

So the final answer is `(x -29y) (x - 1).`

Example2:

To solve the equation:

`(-10x - 4) - (7x - 8) = (-10x - 4) - 7x + 8`

` = -10x-4- 7x + 8`

`=-17x+4`

So the final result is `-17x+4`
