What addresses do not change if you copy them to a different cell.

Mathematics

Valentin [98]2 years ago

Answer:

If you do not want cell references to change when you copy a formula, then make those cell references absolute cell references. Place a "$" before the column letter if you want that to always stay the same. Place a "$" before a row number if you want that to always stay the same.

Answer:

<u>f(x) = 2(x - 2)^2 - 1</u>

<u>vertex: (2, -1)</u>

Step-by-step explanation:

f(x) = 2x^2 - 8x + 7

<em>First, we find the vertex. </em>

x = -(-8)/4 = 2

y = 2(2)^2 - 8(2) + 7 = 2(4) - 16 + 7 = 8 - 9 = -1

vertex: (2, -1)

<em>Second, we write f(x) in vertex form. </em>

<em>we know that h and k have to be 2 and -1. </em>

2x^2 - 8x + 7 = a(x - 2)^2 - 1

<em>Since 8 - 1 = 7, we do this: </em>

f(x) = (2x^2 - 8x + 8) - 1

<em>Factor out the 2 and then factor the polynomial</em>

f(x) = 2(x^2 - 4x + 4) - 1

<em>factors of 4: </em>

1 4

2 2

-1 -4

<u>-2 -2 = -4</u>

<em>the function in vertex for is: </em>

f(x) = 2(x - 2)^2 - 1

1) Split the second term in 3x^{2} -11x-20 into two terms.

3x^{2} +4x-15x-20

2) Factor out common terms in the first two terms, then in the last two terms.

x(3x+4)-5(3x+4)

3) Factor out the common term 3x+4.

(3x+4)(x-5)
