How can I do this exercise? <img src="https://tex.z-dn.net/?f=%5Cfrac%7B-2%7D%7B12%7D%20%3D%20%5Cfrac%7Bx%20%2B%201%7D%7Bx%20%2B
matrenka [14]

Answer:

-8/7 =x

Step-by-step explanation:

-2         x+1

----- = -----------

12         x+2

Using cross products

-2 (x+2) = 12 (x+1)

Distribute

-2x -4 = 12x+12

Add 2x to each side

-2x+2x -4 = 12x+2x+12

-4 = 14x +12

Subtract 12 from each side

-4-12 = 14x

-16 = 14x

Divide each side by 14

-16/14 =14x/14

-8/7 =x

Find g(x), where g(x) is the translation 7 units up of f(x)=x2.
AfilCa [17]

Answer:

g(x)=x^2+7

g(x) in the form a(x-h)^2+k would be:

g(x)=(x-0)^2+7

Step-by-step explanation:

Given:

Parent function:

f(x)=x^2

Translation occurs 7 units up to get g(x)

Translation Rules:

f(x)\rightarrow f(x)+c

If c>0 the function shifts c units to the up.

If c the function shifts c units to the down.

So, from the above rules g(x) can be represented as:

g(x)=f(x)+7     [7 units up]

g(x)=x^2+7

Writing g(x) in the form a(x-h)^2+k where a, h, and\ k are integers.

g(x)=1(x-0)^2+7

g(x)=(x-0)^2+7
