Answer:

Let's solve your equation step-by-step.

3x+2=14

Step 1: Subtract 2 from both sides.

3x+2−2=14−2

3x=12

Step 2: Divide both sides by 3.

3x /3 = 12/3

The following steps are used to rewrite the polynomial expression (x+4y+z)(x-7y)

Georgia [21]

(x+4y+z)(x-7y)= $x^{2} +4xy+xz-7xy-28y-7yz$
= $x^{2} -3xy+xz-7yz$

Given the function f(x) = x3 + x2 − 2x + 1, what is the resulting function when f(x) is shifted to the left 1 unit?

irga5000 [103]

For this case we have the following function:

$f (x) = x ^ 3 + x ^ 2 - 2x + 1$

We apply the following function transformation:

Horizontal translations:

Suppose that h> 0

To graph y = f (x + h), move the graph of h units to the left.

We have then for h = 1:

$f (x + 1) = (x + 1) ^ 3 + (x + 1) ^ 2 - 2 (x + 1) + 1$

Rewriting we have:

$f (x + 1) = (x ^ 3 + 3x ^ 2 + 3x + 1) + (x ^ 2 + 2x + 1) + (-2x - 2) + 1$

Rewriting we have:

$f (x + 1) = x ^ 3 + 4x ^ 2 + 3x + 1$

Answer:

The resulting function when f (x) is shifted to the left 1 unit is:

$f (x + 1) = x ^ 3 + 4x ^ 2 + 3x + 1$
