The graph of y=f(x) is the solid black graph below. Whoch function represents the dotted line
1 answer:
The function that represents the dotted line of the graph using transformation rules is; f(x - 1) - 4.
<h3>How to Interpret Translation of Graphs?</h3>For the function f(x) of the given graph, when we look at the solid line, we see that it has a root at x = -1 which means it has a zero at x = -1.
However, when observing the dashed line, we see that it has a root at x = 0 which means it has a zero at x = 0.
Thus, we can deduce from transformation rules that the function was moved by 1 unit to the right to get the new function.
Secondly, we observe that the dashed line is also below the function f(x), and we observe further that 4 was subtracted. Therefore, when we use the transformation rules again for subtracting from a function, we get the final function as; f(x - 1) - 4.

Answer: This is a type of Synthesis reaction.
Explanation:
- Synthesis reaction is a type of chemical reaction in which two or more substances combine to form a single substance.
- Decomposition reactions are a type of chemical reactions in which a substance breaks down into two or more substances.
- Combustion reaction is a type of chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water.
For the given reaction:
Here, 2 substances are combining together to form a single substance. Hence, it is considered as a synthesis reaction.
