The mapping represents y as a function of x, because each x-value is related to exactly one y-value.

A mapping can be considered to be a function if any of the following conditions met:

Condition : Mapping denotes the relation from Set A to Set B. Relation from A to B is the subsets A $\times$ B. Mapping the oval on the left-hand side denotes the values of Domain and the oval on the right-hand side denotes the values of Range.

1. Every x -value has exactly only 1 possible y-value mapped to it. 2. Two or more x-values can be mapped to the same y-value provided each x-value is not having more than 1 y-value. That is, provided condition 1 is maintained.

Now looking at the mapping given, every x-value you see there is mapped to exactly just 1 y-value. No x-value is mapped to more than 1 y-value.

However, 3 different x-values, -3, 0, and 8, have the same y-values, 4. This also fulfills the condition for a mapping to be regarded as a function, as a y-value of a function can have more than 1 possible x-value mapped to it.

Therefore the mapping represent y as a function of x.

c. The mapping represents y as a function of x, because each x-value is related to exactly one y-value.

Step-by-step explanation:

A mapping can be considered to be a function if any of the following conditions met:

1. Every x-value has exactly only 1 possible y-value mapped to it.

2. Two or more x-values can be mapped to the same y-value provided each x-value is not having more than 1 y-value. That is, provided condition 1 is maintained.

Now looking at the mapping given, every x-value you see there is mapped to exactly just 1 y-value. No x-value is mapped to more than 1 y-value.

Therefore the mapping represents y as a function of x.

The federal reserve controls certain interest rates in the united states. investors often try to speculate as to whether the federal reserve will raise or lower rates and by how much. suppose a company conducts extensive interviews with financial analysts, and as a result, predicts that "thefed" will increase rates by an average of 0.25 percentage points every six months for the forseeable future. which type of equation could be used to model the predicted interest rates over the next several years, assuming no other significant changes? a) a linear equation b) a quadratic equation c) a polynomial equation d) an exponential equation
