The answer is C. The capacity to be free is something that not everybody has. You should be free with a specific end goal to get by on the planet. Figuring out how to bolster yourself is principal for any achievement you ever want to accomplish.

To be useful, chemical equations must always be balanced. Balanced chemical equations have the same number and type of each atom on both sides of the equation.
The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions. mber of atoms of each element in reactants is not equal to the number of atoms of each element present in product, then the chemical equation is called unbalanced chemical equation. An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.
Answer:
out of 100, the decimal is 0.37
Step-by-step explanation:
Answer: 1)
2) see graph
3) Choose one color from the graph
4) D: x ≥ -4
R: y ≥ 0 for or y ≤ 0 for
<u>Step-by-step explanation:</u>
1) To find the inverse, swap the x's and y's and solve for y:
Given: y = x² - 4
Swap: x = y² - 4
x + 4 = y²
2) see attachment. Red and Blue combined creates the graph of the inverse.
3) Choose either the positive (red graph) or the negative (blue graph).
red graph:
blue graph:
4) Domain reflects the x-values of the function. The x-values for the red graph is the same as the blue graph so the answer will be the same regardless of which equation you choose.
Domain: x ≥ 0
Range reflects the y-values of the function. The y-values differ between the positive and negative inverse functions. <em>Positive is above the x-axis. Negative is below the x-axis.</em>
Range (red graph): y ≥ 0 for
Range (blue graph): y ≤ 0 for
