Question

Choose the correct function for the given mapping diagram.
where $x\in \text{Domain}\&y\in \text{Range}$

• A. $y=x+74$
• B. $y=x+47$
• C. $y=x+47,$ where $x$ are the prime numbers between $5$ and $18.$

Answer 1

The correct option is C $y=x+47,$ where $x$ are the prime numbers between $5$ and $18.$

The given mapping diagram follows the equation $y=x+47.$

The values of given domain are $7,11,13$ and $17.$
These are the prime numbers between $5$ and $18.$

According to mapped values of range,
The required function is $y=x+47$
where $x\in \text{Domain}\&y\in \text{Range}$
