Answer:
<h2>B) x² - 4</h2>
Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x + n) - shift the graph n units to the left
f(x - n) - shift the graph n units to the right
------------------------------------------------------------------------------
The vertex of the function f(x) = x² is in the origin.
We have the vertex (0, -4). Therefore, the graph has been moved by 4 units down.
f(x) - 4 = x² - 4
Answer:
15%
Step-by-step explanation:
The price of the tablet was increased from $180 to $207.
Increase = $207 - $180
= $27
Therefore,
Percentage increase = increase/initial amount x 100%
That’s $27/$180 x 100%
0.15 x 100
15%
The percentage increase was 15%

Answer: four raised to the one third power
Step-by-step explanation:
According to the written description, we have the following expression:
![\sqrt{\frac{4}{\sqrt[3]{4}}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B4%7D%7B%5Csqrt%5B3%5D%7B4%7D%7D%7D)
Which can also be written as:
Let's work with this, taking into account the rules of multiplication and division of power with the same base:
Multiplying the exponents:
This is read as "four raised to the one third power"
