Answer:

(5,-6)

Step-by-step explanation:

ONE WAY:

If f(x)=x^2-6x+3, then f(x-2)=(x-2)^2-6(x-2)+3.

Let's simplify that.

Distribute with -6(x-2):

f(x-2)=(x-2)^2-6x+12+3

Combine the end like terms 12+3:

f(x-2)=(x-2)^2-6x+15

Use (x-b)^2=x^2-2bx+b^2 identity for (x-2)^2:

f(x-2)=x^2-4x+4-6x+15

Combine like terms -4x-6x and 4+15:

f(x-2)=x^2-10x+19

We are given g(x)=f(x-2).

So we have that g(x)=x^2-10x+19.

The vertex happens at x=\frac{-b}{2a}.

Compare x^2-10x+19 to ax^2+bx+c to determine a,b,\text{ and } c.

a=1

b=-10

c=19

Let's plug it in.

\frac{-b}{2a}

\frac{-(-10)}{2(1)}

\frac{10}{2}

5

So the x- coordinate is 5.

Let's find the corresponding y- coordinate by evaluating our expression named g at x=5:

5^2-10(5)+19

25-50+19

-25+19

-6

So the ordered pair of the vertex is (5,-6).

ANOTHER WAY:

The vertex form of a quadratic is a(x-h)^2+k where the vertex is (h,k).

Let's put f into this form.

We are given f(x)=x^2-6x+3.

We will need to complete the square.

I like to use the identity x^2+kx+(\frac{k}{2})^2=(x+\frac{k}{2})^2.

So If you add something in, you will have to take it out (and vice versa).

x^2-6x+3

x^2-6x+(\frac{6}{2})^2+3-(\frac{6}{2})^2

(x+\frac{-6}{2})^2+3-3^2

(x+-3)^2+3-9

(x-3)^2+-6

So we have in vertex form f is:

f(x)=(x-3)^2+-6.

The vertex is (3,-6).

So if we are dealing with the function g(x)=f(x-2).

This means we are going to move the vertex of f right 2 units to figure out the vertex of g which puts us at (3+2,-6)=(5,-6).

The y- coordinate was not effected here because we were only moving horizontally not up/down.

<span>x^2 + 12x = 11

</span><span>x^2 + 12x + 36 = 11 + 36

</span>(x + 6)^2 = 47

answer

the number should be added to both sides <span>of the equation to complete the square = 36</span>
