Which of the following functions is graphed below?
Butoxors [25]

Answer:

Option (B)

Step-by-step explanation:

Given question is not complete; find the complete question in the attachment.

In the graph attached,

Parent function is an absolute value function,

f(x) = |x|

When this graph is shifted 4 units left, rule for the translation will be,

f(x) → f(x + 4)

Therefore, the new function of above translation will be,

g(x) = f(x + 4) = |x + 4|

Now the graph is shifted 2 units down so the translated function will be,

h(x) = g(x) - 2

h(x) = |x + 4| - 2

If we rewrite the function in the form of an equation, graph will be represented by

⇒ y = |x + 4| - 2

Therefore, Option (B) will be the answer.

Korolek [52]

Answer:

Step-by-step explanation:

245000 last year

This year 25235

(y2 - y1) / y1)*100 = your percentage change

(where y1=start value and y2=end value)  

(( £25.235 - £24.500) / £24.500) * 100 = 0 %

There ain't no percentage change as there needs to be a bigger difference between the two numbers plus u should use the formula

Step-by-step explanation:

Given:

Data Plan for Shawn's Phone = 32000 megabytes.

She want to increase the data by 4% = \frac{4}{32000}\times 100= 1280 megabytes

Each Photo uses 5 megabytes so 200 additional Photo will require =5\times200= 1000\ megabytes

She has 1280 megabytes of additional data and requires 1000 megabytes to upload 200 photos, so she have enough memory to do so.
