Answer:

y = -(x - 2)^2.

Step-by-step explanation:

Vertex form is a(x - b)^2 + c where a is a constant and (b, c) is the vertex.

Here b = 2 and c = 0

So we have:

y = a( x - 2)^2 + 0

When x = 4 y = -4 so:

-4 = a( 4 - 2)^2

a = -4/2^2 = -1

So the required equation is

y = -(x - 2)^2.

Answer: four raised to the one third power

Step-by-step explanation:

According to the written description, we have the following expression:

$\sqrt{\frac{4}{\sqrt[3]{4}}}$

Which can also be written as:

$(\frac{4}{4^{\frac{1}{3}}})^{\frac{1}{2}}$

Let's work with this, taking into account the rules of multiplication and division of power with the same base:

$(4^{1-\frac{1}{3}} )^{\frac{1}{2}}=(4^{\frac{2}{3}})^{\frac{1}{2}}$

Multiplying the exponents:

$4^{\frac{1}{3}}$ This is read as "four raised to the one third power"
