Answer:

k(x) = 2x
k(x) = 2x -7
k(x) = 2x -1
k(x) = 2x -8

Step-by-step explanation:

Vertical translation adds the amount of upward translation to the value of the function. Upward translation by 'v' units will make the new function ...

k(x) = f(x) +v

We assume your f(x) is 2x -3.

Up 3 units

k(x) = f(x) +3 = 2x -3 +3

k(x) = 2x

Down 4 units

k(x) = f(x) -4 = 2x -3 -4

k(x) = 2x -7

Up 2 units

k(x) = f(x) +2 = 2x -3 +2

k(x) = 2x -1

Down 5 units

k(x) = f(x) -5 = 2x -3 -5

k(x) = 2x -8

Write a quadratic equation ax²+ bx + C = 0, whose coefficients are a =-9, b = 0, c = -2

aksik [14]

Let's write -9 where we see A:

Let's write 0 where we see B:

(Since B = 0, when it is multiplied by x, it becomes 0 again)

Let's write -2 where we see C:

Now we can move on to solving our equation:)

Let's put the known and the unknown on different sides:

(-2 goes to the opposite side positively)

(it goes as a division because it is in the case of multiplying -9 across)

 

I could not find the rest of it, but I did not want to delete it for trying very hard. Sorry. It felt like we should take the square root, but I couldn't find it, maybe this can help you a little bit.

Please do not report:(

I hope I got it right, I'm trying to improve my English a little :)
