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.

<u>Up 3 units</u>

  k(x) = f(x) +3 = 2x -3 +3

  k(x) = 2x

<u>Down 4 units</u>

  k(x) = f(x) -4 = 2x -3 -4

  k(x) = 2x -7

<u>Up 2 units</u>

  k(x) = f(x) +2 = 2x -3 +2

  k(x) = 2x -1

<u>Down 5 units</u>

  k(x) = f(x) -5 = 2x -3 -5

  k(x) = 2x -8

In the function f(x)=6x^2-4, what is the value of f(-2)?
BartSMP [9]

In order to find the value of f(-2), you can plug -2 wherever x is.

f(x) = 6x^2 - 4

f(-2) = 6(-2)^2 - 4

f(-2) = 6(4) - 4

f(-2) = 24 - 4

f(-2) = 20

Thus, the value of f(-2) is 20. Hope this helps! If you have any other questions related to this, let me know.

How do you do question b?
notsponge [240]

Part (b)

We use the result of part (a) and plug in (x,y) = (0,0). This is directly from the initial condition y(0) = 0.

\arcsin(4y) = x^2 + C\\\\\arcsin(4*0) = (0)^2 + C\\\\\arcsin(0) = C\\\\0 = C\\\\C = 0\\\\

-----------------

This means,

\arcsin(4y) = x^2 + C\\\\\arcsin(4y) = x^2 + 0\\\\\arcsin(4y) = x^2\\\\4y = \sin(x^2)\\\\y = \frac{1}{4}\sin(x^2)\\\\

is the solution with the initial condition y(0) = 0.

A carpenter purchased 50 ft of redwood and 80 ft of pine for a total cost of $285. A second purchase, at the same prices, includ
Marizza181 [45]

Hey there!!

Let us take the price of the redwood as ' x ' and pine as ' y '

Then , we take it into an equation. We get,

50x + 80y = 285 -------------- ( 1 )

80x + 50y = 339 -------------- ( 2 )

Now, multiply the first equation with 8 and the second equation with 5

400x + 640y = 2280

400x + 250y = 1695

Now subtract the second equation from the first

390y = 585

y = 585 / 390

y = $1.5

Now substitute this into any equation

50x + ( 80 ) ( 1.5 ) = 285

50x + 120 = 285

50x = 165

x = 165 / 50

x = $3.3

Redwood = $3.3

Pine = $1.5

Hope helps!
