Is (x − 4) a factor of f(x) = x3 − 2x2 + 5x + 1? Use either the remainder theorem or the factor theorem to explain your reasonin

AlladinOne [14]

Answer:

No, not a factor.

Step-by-step explanation:

By solving for (x-4) and getting x = 4, if we take that value and subtititute it into the original function, it should result in 0 IF it was a factor of the original function.

After substituting it in, you get a vbalue other than 0, meaning that by the factor theorem, (x-4) is not a factor.

F(x) = x^2-5 g(x) = 4x - 4 Find (f-g) (5)

Tresset [83]

Answer:

The correct answer option is: 4.

Step-by-step explanation:

We are given the following two functions and we are to find the value of $( f - g ) ( 5 )$ :

$f(x) = x^2 - 5$

$g(x) = 4x - 4$

Finding $( f - g ) ( x )$ :

$( f - g ) ( x )$ $= (x^2-5)-(4x-4) = x^2-4x-5+4$

$( f - g ) ( x ) = x^2-4x-1$

So, $( f - g ) ( 5 ) = (5)^2-4(5)-1 = 4$

Alberto uses the steps below to solve the equation One-half x minus 3 equals 7. Step 1: One-half x minus 3 plus 3 equals 7 plus

natka813 [3]

Answer:

Identity property of multiplication

Step-by-step explanation:

From step 5:

$1x = 20$

Here, to solve for x so that the variable x stands alone, Alberto uses the identity property of multiplication, which justifies what he has in step 6.

Step 6:

$x = 20$

According to the identity property of multiplication, any value you multiply by 1 gives you that same value.

Therefore, 1x = 1 × x = x.

The variable x multiplied by 1 will give you x.
