The parent function y = |x| stretched vertically by a factor of 2, shifted left 3 units and down 4 units

OlgaM077 [116]

Hello!

Let's go through some formula to distinguish the changes that happen to a graph's equation when they are transformed.

Vertical shifts have this type of formula:

f(x) + k → up k units and f(x) - k → down k units

Horizontal shifts have this type of formula:

f(x + k) → left k units and f(x - k) → right k units

Reflections have this type of formula:

-f(x) → reflect over x-axis and f(-x) → reflect over y-axis

Vertical stretches have this type of formula:

a · f(x) where a > 1

Vertical compressions have this type of formula:

a · f(x) where a < 1

Horizontal stretches have this type of formula:

f(a · x) where a > 1

Horizontal compressions have this type of formula:

f(a · x) where a < 1

With that in mind, we can write our transformed absolute value function.

Since the equation is vertically stretched by a factor of 2, a = 2.

y = 2|x|

Also, since the function is shifted left 3 units, k = -3.

y = 2|x + 3|

Finally, the function is also shifted down 4 units, so k = -4.

y = 2|x + 3| - 4

Therefore, the equation is y = 2|x + 3| - 4.

Answer:

The price per share after 4 hours is $21.43

The price per share after 20 hours is $4.15

Step-by-step explanation:

Equations

The price of the company's stock is initially at $25.75 per share. Each hour the price drops by $1.08. This condition can be modeled by the function:

$P(t)=25.75-1.08t$

Where t is the time in hours.

The sign means the function is decreasing as time passes.

When t=4 hours, the price will be:

$P(4)=25.75-1.08\cdot 4=21.43$

The price per share after 4 hours is $21.43

Now find the price when t=20 hours

$P(20)=25.75-1.08\cdot 20=4.15$

The price per share after 20 hours is $4.15

Need help solving this

kari74 [83]

The ratio is -3 , find this be dividing two consecutive numbers:

-6/2 =-3

18/-6 = -3

-54/18 =-3

The 5th number in the sequence would be -54 x -3 = 162

The 6th number will be 162 x -3 = -486

The answer is the 3rd choice.
