SAT
1 answer:
monitta2 years ago
3 0

Answer:

True

Explanation:

When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction. An exothermic reaction is a term that describes a chemical reaction in which there is a net release of energy (heat).

Given the function f(x) = 3(x – 2)2 + 4 with a restricted domain of x ≥ 2, which of the following represents f–1(x)?.
Debora [2.8K]

The inverse of the function is f^{-1}x= \sqrt{\frac{x-4}{3} } + 2

<h3 /><h3>Domain and Range of functions</h3>

Given the function

f(x) = 3(x - 2)^2 + 4

To get the inverse, you will follow the same step as shown:

Rewrite the equation to have:

y= 3(x - 2)^2 + 4

Replace x with y

x = 3(y - 2)^2 + 4

<h3>Make y the subject of the formula</h3>

x = 3(y - 2)^2 + 4\\x-4=3(y - 2)^2\\\frac{x-4}{3} = (y-2)^2\\ y-2=\sqrt{\frac{x-4}{3} } \\y = \sqrt{\frac{x-4}{3} } + 2

Hence the inverse of the function is f^{-1}x= \sqrt{\frac{x-4}{3} } + 2
